The mechanical measure of population control includes

Options

A. Condom only
B. Diaphragm only
C. IUD only
D. All of the above

Answer

To solve the question regarding the mechanical measures of population control, we will analyze each option provided and determine if they fall under the category of mechanical measures or barrier methods of contraception.

### Step-by-Step Solution:

1. **Understanding Mechanical Measures**: Mechanical measures of population control refer to methods that physically prevent fertilization. These are often categorized as barrier methods, which block the sperm from reaching the egg.

2. **Evaluating the Options**:
- **Option A: Condom**: Condoms are a barrier method used by males. They are made of latex or rubber and prevent sperm from entering the female reproductive system. This method effectively reduces the chances of fertilization.
- **Option B: Diaphragm**: Diaphragms are dome-shaped devices used by females. They are inserted into the vagina to cover the cervix and prevent sperm from entering the uterus. This is also a barrier method.
- **Option C: IUD (Intrauterine Device)**: IUDs are devices placed inside the uterus by a healthcare professional. They can be made of copper or contain hormones. While they function differently from condoms and diaphragms, they are still considered a mechanical form of contraception as they prevent fertilization by creating an environment that is hostile to sperm.

3. **Conclusion**: Since all three options (condom, diaphragm, and IUD) are methods that prevent fertilization, they all qualify as mechanical measures of population control. Therefore, the correct answer is **all of the above**.

### Final Answer:
**All of the above** (Condom, Diaphragm, IUD)
