Assertion : Koel does not build nest for egg laying.
Reason : Koel lays its eggs in the nest of tailor bird.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reson are false.

Explanation

To solve the assertion and reason question, we need to evaluate both statements separately and determine their validity.

### Step 1: Analyze the Assertion
- **Assertion**: "Koel does not build nest for egg laying."
- The koel, which is a type of cuckoo bird, is known for its behavior of not building its own nest. Instead, it lays its eggs in the nests of other birds. This behavior is a characteristic of brood parasitism. Therefore, the assertion is **true**.

### Step 2: Analyze the Reason
- **Reason**: "Koel lays its eggs in the nest of tailor bird."
- The koel typically lays its eggs in the nests of other birds, but it is commonly known to lay its eggs in the nests of crows, not tailor birds. The tailor bird is known for its unique nest-building behavior, but it is not the host for koel eggs. Therefore, this statement is **false**.

### Step 3: Conclusion
- Since the assertion is true and the reason is false, we can conclude that the correct relationship is that the assertion is correct, but the reason is incorrect.

### Final Answer
The correct answer is that the assertion is true, but the reason is false.
