B. I - D, II - B, III - C, IV - A
C. I - D, II - C, III - B, IV - A
D. I - D, II - C, III - A, IV - B

Answer

To solve the matching question, we need to pair the items from Column I with the correct descriptions from Column II. Let's analyze each item step by step.

### Step-by-Step Solution:

1. **Acrosome**:
- The acrosome is a cap-like structure found on the head of spermatozoa (sperm cells). It contains enzymes that help the sperm penetrate the egg's outer layers during fertilization.
- **Match**: Acrosome → (D) Spermatozoan.

2. **Endometrium**:
- The endometrium is the inner lining of the uterus where the embryo implants after fertilization. It plays a crucial role in the menstrual cycle and pregnancy.
- **Match**: Endometrium → (B) Uterus.

3. **Polar Body**:
- Polar bodies are small cells that are produced during oogenesis (the formation of eggs) but do not develop into ova. They are a byproduct of meiosis in oocytes.
- **Match**: Polar Body → (C) Oogenesis.

4. **Clitoris**:
- The clitoris is a small, sensitive organ located at the top of the vulva, composed of erectile tissue. It plays a significant role in female sexual arousal.
- **Match**: Clitoris → (A) Rudimentary erectile tissue.

### Final Matches:
- I. Acrosome → (D) Spermatozoan
- II. Endometrium → (B) Uterus
- III. Polar Body → (C) Oogenesis
- IV. Clitoris → (A) Rudimentary erectile tissue
