Answer

To determine which statement is incorrect regarding the diaphragm, cervical cap, and vaults, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding the Barrier Methods**:
- Diaphragm, cervical cap, and vaults are all forms of barrier contraception. They work by physically blocking sperm from entering the uterus.

2. **Evaluating Statement 1**:
- **Statement**: "These prevent conception by blocking the entry of the sperm through the cervix."
- **Analysis**: This statement is correct. The diaphragm and cervical cap are designed to cover the cervix, preventing sperm from entering the uterus.

3. **Evaluating Statement 2**:
- **Statement**: "These are made up of rubber that are inserted into the female reproductive tract to cover the cervix."
- **Analysis**: This statement is also correct. Diaphragms and cervical caps are often made from materials like rubber or silicone and are inserted into the vagina to cover the cervix.

4. **Evaluating Statement 3**:
- **Statement**: "These provide additional benefit of protecting the user from contracting STD and AIDS."
- **Analysis**: This statement is incorrect. While barrier methods like condoms can help prevent sexually transmitted diseases (STDs), diaphragms and cervical caps do not provide significant protection against STDs, including AIDS.

5. **Evaluating Statement 4**:
- **Statement**: "These are reusable."
- **Analysis**: This statement is correct. Diaphragms and cervical caps can be washed, air-dried, and reused multiple times.

### Conclusion:
The incorrect statement regarding diaphragm, cervical cap, and vaults is **Statement 3**: "These provide additional benefit of protecting the user from contracting STD and AIDS."
