Condoms are one of the most popular contraceptives because of the following reasons.

Options

A. These are effective barriers for insemination
B. They do not interfere with coital act.
C. These help in reducing the risk of STDs.
D. All of the above

Explanation

**Step-by-Step Solution:**

1. **Understanding the Function of Condoms**: Condoms are designed primarily as a barrier method of contraception. They prevent sperm from entering the female reproductive tract, thereby reducing the chances of fertilization.

2. **Effective Barrier**: The first reason condoms are popular is that they act as an effective barrier against insemination. By preventing sperm from reaching the ovum, they significantly reduce the likelihood of pregnancy.

3. **Non-Interference with Sexual Intercourse**: The second reason is that condoms do not interfere with sexual intercourse. They are designed to be worn by the male partner and are made of thin latex or rubber, allowing for a natural feel during sexual activity.

4. **Reduction of Sexually Transmitted Diseases (STDs)**: The third reason is that condoms help reduce the risk of sexually transmitted diseases. They provide a protective barrier that can prevent the exchange of bodily fluids, which is a common way STDs are transmitted.

5. **Conclusion**: Since all three reasons are valid, the correct answer to the question is that all of the above options are correct. Therefore, the answer is D: All of the above.
