[A]: Oral contraceptive pills are meant for family planning purpose.
[R]: Oral contraceptive pills inhibit fertilization

Options

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

Answer

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

### Step 1: Analyze the Assertion
**Assertion (A): Oral contraceptive pills are meant for family planning purposes.**

- Oral contraceptive pills (OCPs) are indeed designed for family planning. They are a form of contraception that helps individuals or couples control the number of children they wish to have.
- OCPs are widely recognized as a method of birth control.

**Conclusion for Step 1:** The assertion is true.

### Step 2: Analyze the Reason
**Reason (R): Oral contraceptive pills inhibit fertilization.**

- Oral contraceptive pills primarily work by altering hormonal levels in the body. They contain hormones such as estrogen and progesterone.
- The primary mechanism of OCPs is to prevent ovulation (the release of an egg from the ovaries). If ovulation does not occur, there is no egg available for fertilization.
- Additionally, OCPs can also alter the uterine lining, making it less suitable for implantation, but they do not directly inhibit fertilization itself.

**Conclusion for Step 2:** The reason is misleading. While OCPs prevent pregnancy, they do so mainly by preventing ovulation rather than directly inhibiting fertilization. Therefore, the reason is false.

### Step 3: Determine the Relationship
- Since the assertion is true and the reason is false, we conclude that the correct answer is that the assertion is true, but the reason is false.

### Final Answer
- Assertion is true; Reason is false.
