Options

A. If both Assertion and Reason are true but the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion and Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true but Reason is false, then mark (3).
D. If both Assertion and Reason are false, then mark (4).

Answer

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Surgical methods of contraception are practiced to space two successive conceptions."
- Surgical methods of contraception, such as vasectomy and tubectomy, are primarily used for sterilization, which means they are intended to prevent any future pregnancies rather than just spacing them. Therefore, this assertion is **false**.

2. **Understanding the Reason**:
- The reason states that "During surgical methods, ovaries from females or testes from males are removed."
- In reality, surgical contraception does not involve the removal of ovaries or testes. Instead, it involves cutting and tying the fallopian tubes in females (tubectomy) or cutting and tying the vas deferens in males (vasectomy). Therefore, this reason is also **false**.

3. **Conclusion**:
- Since both the assertion and the reason are false, we can conclude that the correct answer is option 4: "Both assertion and reason are false."

### Final Answer:
Both assertion and reason are false.
