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 reason are false.

Answer

To analyze the given assertion and reason, let's break it down step by step:

### Step 1: Understand the Assertion
- **Assertion**: "Conditioned reflex is not present at birth."
- This statement is true. Conditioned reflexes are learned behaviors that develop through experience and interaction with the environment. They are not innate or present from birth.

### Step 2: Understand the Reason
- **Reason**: "Initially these actions require learning and after perfection these become involuntary actions."
- This statement is also true. Conditioned reflexes begin as voluntary actions that require learning. Over time, with practice and repetition, these actions can become automatic or involuntary.

### Step 3: Analyze the Relationship between Assertion and Reason
- The reason explains why the assertion is true. Since conditioned reflexes require learning and are not present at birth, the reason supports the assertion effectively.

### Step 4: Conclusion
- Both the assertion and reason are true, and the reason provides a correct explanation for the assertion. Therefore, the correct answer is:
- **Option 1**: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
