Reason : Barrier methods are used during coitus, to prevent the entry of ejaculated semen into the female reproductive tract.

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 reason are false

Explanation

To solve the assertion and reason question, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "In barrier methods, ovum and sperm are prevented from physical meetings."
- Barrier methods, such as condoms and diaphragms, physically block sperm from reaching the ovum. Therefore, this assertion is true.

2. **Understanding the Reason**:
- The reason states that "Barrier methods are used during coitus to prevent the entry of ejaculated semen into the female reproductive tract."
- Barrier methods are indeed employed during sexual intercourse (coitus) to prevent sperm from entering the female reproductive system. This statement is also true.

3. **Evaluating the Relationship**:
- The reason provides an explanation for the assertion. It clarifies how barrier methods function to prevent the meeting of ovum and sperm by blocking the entry of semen during coitus.
- Since the reason accurately explains the assertion, we can conclude that both statements are true, and the reason is a correct explanation of the assertion.

4. **Choosing the Correct Option**:
- Based on the analysis, the correct option is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer:
- Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
