C. Reusable for males only
D. None

Answer

**Step-by-Step Solution:**

1. **Identify the Items**: The question mentions diaphragms, cervical caps, and vaults. These are all contraceptive devices used in reproductive health.

2. **Understand Their Function**: These devices act as barriers. They are inserted into the female reproductive tract to cover the cervix during sexual intercourse (coitus), preventing sperm from entering the uterus.

3. **Material Composition**: Diaphragms, cervical caps, and vaults are typically made of rubber or silicone, which allows them to be flexible and form a seal.

4. **Reusability**: Unlike condoms, which are designed for single use, diaphragms, cervical caps, and vaults are reusable. They can be cleaned and used multiple times.

5. **Evaluate the Options**:
- Option 1: Reusable - This is correct as these devices can be used multiple times.
- Option 2: Non-reusable - This is incorrect as they are reusable.
- Option 3: Reusable for males only - This is incorrect as these devices are specifically for females.
- Option 4: None - This is incorrect as option 1 is valid.

6. **Conclusion**: The correct answer is option 1: Reusable.
