Which of the following can protect the user from contracting AIDS?

Options

A. condoms
B. pills
C. IUD
D. All of these

Answer

### Step-by-Step Solution:

1. **Understanding AIDS Transmission**:
- AIDS (Acquired Immunodeficiency Syndrome) is primarily transmitted through body fluids such as blood, semen, vaginal secretions, and breast milk. It is a sexually transmitted disease (STD).

2. **Identifying Preventive Methods**:
- To prevent contracting AIDS, it is essential to use methods that create a barrier to these body fluids during sexual intercourse.

3. **Evaluating Options**:
- The question likely provides multiple options. We need to assess each option to determine which one effectively prevents the transmission of AIDS.

4. **Barrier Methods**:
- Barrier methods, such as condoms, are designed to prevent direct contact with body fluids. They act as a physical barrier that stops the exchange of fluids between partners.

5. **Analyzing Other Methods**:
- Oral contraceptive pills and intrauterine devices (IUDs) are not effective in preventing the transmission of AIDS. While they may prevent pregnancy, they do not stop the exchange of body fluids, which is necessary to prevent the transmission of STDs.

6. **Conclusion**:
- Based on the analysis, the correct answer is the use of condoms, as they are the only method listed that can effectively protect against contracting AIDS.

### Final Answer:
- **Condoms (Option 1)** are the correct choice for protecting the user from contracting AIDS.
