C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4).

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that the use of condoms is a safeguard against AIDS and other sexually transmitted diseases (STDs), in addition to preventing pregnancy. This is true because condoms are effective barriers that can prevent the exchange of bodily fluids, which is the primary way STDs, including HIV/AIDS, are transmitted.

2. **Understanding the Reason**: The reason provided states that certain contraceptives are implanted under the skin of the upper arm to prevent pregnancy. This is also true. An example of such a contraceptive is Nexplanon, which is a flexible plastic rod that releases hormones (progestogens) to prevent ovulation and thus pregnancy.

3. **Analyzing the Relationship**: While both the assertion and the reason are true statements, the reason does not explain the assertion. The assertion focuses on the protective role of condoms against STDs, while the reason discusses a different method of contraception that does not relate to the use of condoms.

4. **Conclusion**: Since both statements are true but the reason does not correctly explain the assertion, the correct answer is that both statements are true, but the reason is not the correct explanation of the assertion.

### Final Answer:
Both the assertion and the reason are true, but the reason is not the correct explanation of the assertion.
