The correct Answer is:
To solve the question, we will analyze each statement one by one and determine whether they are true or false. ### Step-by-Step Solution: **Step 1: Analyze Statement I** - Statement: "Plastics are generally good conductors of electricity." - Analysis: This statement is **false**. Plastics are generally considered to be poor conductors of electricity; they are insulators. **Step 2: Analyze Statement II** - Statement: "Ropes made of bakelite are used in cranes and elevators." - Analysis: This statement is also **false**. Bakelite is a type of plastic that is not typically used for ropes. Instead, materials like nylon are used in cranes and elevators due to their strength and flexibility. **Step 3: Analyze Statement III** - Statement: "Teflon is a special plastic on which oil and water do not stick." - Analysis: This statement is **true**. Teflon is known for its non-stick properties, making it ideal for cookware, as oil and water do not adhere to its surface. **Step 4: Analyze Statement IV** - Statement: "Plastic is non-biodegradable, hence not environment friendly." - Analysis: This statement is **true**. Most plastics are non-biodegradable, meaning they do not break down naturally in the environment, which contributes to pollution and environmental issues. ### Conclusion: - Statement I: False - Statement II: False - Statement III: True - Statement IV: True Thus, the correct option based on the analysis is that the first two statements are false, and the last two statements are true. ### Final Answer: The correct option is the one that states: **"False, False, True, True."** ---

To solve the question, we will analyze each statement one by one and determine whether they are true or false. ### Step-by-Step Solution: **Step 1: Analyze Statement I** - Statement: "Plastics are generally good conductors of electricity." - Analysis: This statement is **false**.
