The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "The body of hemichordates is divisible into proboscis, collar, and trunk." - Hemichordates are a group of marine animals that indeed have a body structure divided into three distinct parts: the proboscis (anterior part), the collar (middle part), and the trunk (posterior part). - Therefore, the assertion is **true**. 2. **Understanding the Reason**: - The reason states that "Proboscis gland helps in digestion." - However, the function of the proboscis in hemichordates is primarily related to excretion, not digestion. The proboscis is involved in various functions, but the gland associated with it does not aid in digestion. - Therefore, the reason is **false**. 3. **Conclusion**: - Since the assertion is true and the reason is false, the correct relationship is that the assertion is correct, but the reason is incorrect. ### Final Answer: - The assertion is true, but the reason is false. Therefore, the answer is option C. ---
