The correct Answer is:
To solve the question, we will analyze both the assertion and the reason provided. ### Step 1: Analyze the Assertion The assertion states that "Ethanol is obtained commercially by fermentation of molasses." - **Explanation**: Molasses is a byproduct of sugar production, which contains sugars that can be fermented. During fermentation, yeast converts these sugars into ethanol (alcohol) and carbon dioxide. This process is indeed a common commercial method for producing ethanol. ### Step 2: Analyze the Reason The reason states that "Fermentation takes place in aerobic conditions." - **Explanation**: Fermentation is a metabolic process that occurs in the absence of oxygen (anaerobic conditions). In aerobic conditions, the process would lead to complete oxidation of sugars into carbon dioxide and water, rather than the production of ethanol. Therefore, this statement is incorrect. ### Step 3: Conclusion - The assertion is true because ethanol is indeed produced from the fermentation of molasses. - The reason is false because fermentation occurs under anaerobic conditions, not aerobic conditions. ### Final Answer Thus, the correct conclusion is that the assertion is true, but the reason is false. Therefore, the correct answer is option C: Assertion is true, Reason is false. ---
