Which one of the following is a barrier method of contraception?

Options

A. tubectomy
B. IUCD
C. Diaphragm
D. Contraceptive pill

Answer

To determine which option is a barrier method of contraception, we can analyze each option provided in the question. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Concept of Barrier Methods
Barrier methods of contraception are designed to prevent sperm from reaching the ovum, thereby preventing fertilization. They physically block the sperm's path.

### Step 2: Analyze Each Option
1. **Tubectomy**: This is a surgical method of sterilization where the fallopian tubes are cut to prevent eggs from traveling to the uterus. This method does not act as a barrier but rather as a permanent solution to prevent pregnancy.

2. **IUD (Intrauterine Device)**: IUDs are inserted into the uterus and can prevent fertilization, but they do not act as a barrier in the traditional sense of blocking sperm. They work by creating an environment that is not conducive to fertilization or implantation.

3. **Diaphragm**: This is a dome-shaped device made of rubber that is inserted into the vagina to cover the cervix. It acts as a physical barrier to prevent sperm from entering the uterus, making it a true barrier method of contraception.

4. **Contraceptive Pills**: These are hormonal methods that prevent ovulation and do not involve any physical barrier to sperm.

### Step 3: Identify the Correct Answer
Based on the analysis:
- The only option that fits the definition of a barrier method of contraception is **Diaphragm**.

### Final Answer
The correct answer is **Diaphragm**.
