The correct Answer is:
To solve the assertion and reason question regarding air layering and vegetative propagation, we will follow these steps: ### Step 1: Understand the Assertion The assertion states that "air layering is performed in those plants which have many long flexible branches near the soil level." - **Analysis**: Air layering is a method of vegetative propagation where a branch is induced to root while still attached to the parent plant. It does not necessarily require long flexible branches near the soil level; it can be performed on various branches of a plant. ### Step 2: Understand the Reason The reason states that "layering method of vegetative propagation is performed in monocot plants." - **Analysis**: The layering method, including air layering, is primarily used in dicot plants, not monocots. Monocots typically do not propagate through layering methods. ### Step 3: Determine the Correctness of Assertion and Reason - **Assertion**: Incorrect (air layering does not require long flexible branches near the soil). - **Reason**: Incorrect (layering is not primarily performed in monocots; it is mainly used in dicots). ### Step 4: Evaluate the Relationship Between Assertion and Reason Since both the assertion and the reason are incorrect, the reason does not explain the assertion. ### Step 5: Choose the Correct Option Given that both the assertion and the reason are incorrect, the correct option is: - **Option D**: Both assertion and reason are incorrect. ### Summary of the Solution - Assertion: Incorrect - Reason: Incorrect - Correct Option: D (Both assertion and reason are incorrect) ---

    Many United States companies have, unfortunately, made the search for legal protection from import competition into a major line of work. Since 1980 the United States International Trade Commission (ITC) has received about 280 complaints alleging damage from imports that benefit from subsidies by foreign governments. Another 340 charge that foreign companies "dumped" their products in the United States at "less than fair value." Even when no unfair practices are alleged, the simple claim that an industry has been injured by imports is sufficient grounds to seek relief. Contrary to the general impression, this quest for import relief has hurt more companies than it has helped. As corporations begin to function globally, they develop an intricate web of marketing, production, and research relationships, The complexity of these relationships makes it unlikely that a system of import relief laws will meet the strategic needs of all the units under the same parent company. Internationalization increases the danger that foreign companies will use import relief laws against the very companies the laws were designed to protect. Suppose a United States-owned company establishes an Overseas plant to manufacture a product while its competitor makes the same product in the United States. If the competitor can prove injury from the imports and that the United States company received a subsidy from a foreign government to build its plant abroad - the United States company's products will be un competitive in the United States, since they would be subject to duties. Perhaps the most brazen case occurred when the ITC investigated allegations that Canadian companies were injuring the United States salt industry by dumping rock salt, used to de-ice roads. The bizarre aspect of the complaint was that a foreign conglomerate with United States operations was crying for help against a United States company with foreign operations. The "United States” company claiming injury was a subsidiary of a Dutch conglomerate, while the "Canadian" companies included a subsidiary of a Chicago firm that was the second-largest domestic producer of rock salt. In paragraph 3 performs which of the following functions in the passage?
