Assertion (A): Composite fish culture involves the cultivation of different varieties of fish having same feeding habits.
Reason (R): Different varieties of fish utilize different areas of the same pond for their feed.

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true, but R is not the correct explanation of A
C. A is true but R is false
D. A is false but R is true

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion (A):** The assertion states that "Composite fish culture involves the cultivation of different varieties of fish having the same feeding habits." This means that in composite fish culture, the fish species grown together should ideally have similar dietary needs.

2. **Evaluating the Reason (R):** The reason given is that "Different varieties of fish utilize different areas of the same pond for their feed." This suggests that even if the fish have different feeding habits, they can coexist in the same pond by occupying different feeding zones.

3. **Analyzing the Assertion:** In composite fish culture, the goal is to maximize the use of resources in a pond. This is typically achieved by cultivating fish species that have different feeding habits, allowing them to occupy various niches and utilize different food sources efficiently. Therefore, the assertion is incorrect.

4. **Analyzing the Reason:** The reason states that different fish can feed in different areas of the pond. This is true and aligns with the principles of aquaculture where different species can coexist by exploiting different ecological niches.

5. **Conclusion:** Since the assertion is false and the reason is true, we conclude that the correct option is that the assertion is incorrect while the reason is correct.

**Final Answer:** The assertion (A) is false, and the reason (R) is true.
