II. Clitoris
III. Seminiferqus tubules
IV. Polar body
Column II
(A) Homologous to penis
(B) Testis
(C) Connection of scrotum with abdomen
(D) Oogenesis

Options

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

Answer

To solve the matching question between Column I and Column II, we need to analyze each item in Column I and find its corresponding match in Column II.

### Step-by-Step Solution:

1. **Inguinal Canal**:
- The inguinal canal is a passage that connects the scrotum to the abdomen. It allows for the descent of the testis during development.
- **Match**: (C) Connection of scrotum with abdomen.

2. **Clitoris**:
- The clitoris is a part of the female external genitalia and is homologous to the penis in males, meaning they share a common embryonic origin.
- **Match**: (A) Homologous to penis.

3. **Seminiferous Tubules**:
- The seminiferous tubules are located within the testis and are responsible for the production of sperm. They are considered the structural and functional units of the testis.
- **Match**: (B) Testis.

4. **Polar Body**:
- The polar body is a byproduct of oogenesis (the formation of ova in females). It is formed during the meiotic divisions of oocytes and is much smaller than the ovum.
- **Match**: (D) Oogenesis.

### Final Matches:
- I. Inguinal canal → (C) Connection of scrotum with abdomen
- II. Clitoris → (A) Homologous to penis
- III. Seminiferous tubules → (B) Testis
- IV. Polar body → (D) Oogenesis

### Conclusion:
The correct matches are:
- I - C
- II - A
- III - B
- IV - D

Thus, the answer is option 4.
