Mathc column I with column II and select the correct option from the codes given below.
`{:("Column I","Column II"),("Hypothalamus",(i)"Sperm lysins"),("Acrosome",(ii)"Estrogen"),("Graafian foolicle",(iii)"Relaxin"),("Parturiton",(iv)"Testosterone"):}`

Options

A. iv,I,ii,iii,v
B. ii,iiv,iii,v
C. ii,I,v,iv,iii
D. iv,I,ii,v,iii

Answer

To solve the matching question between Column I and Column II, we will analyze each item in Column I and identify the corresponding item in Column II.

### Step-by-Step Solution:

1. **Hypothalamus**:
- The hypothalamus is responsible for releasing gonadotropin-releasing hormone (GnRH), which stimulates the anterior pituitary to release hormones like FSH and LH. These hormones then act on the testes to produce testosterone.
- **Match**: Hypothalamus → (iv) Testosterone

2. **Acrosome**:
- The acrosome is a part of the sperm that contains enzymes necessary for fertilization. It releases enzymes such as hyaluronidase and acrosin, which help the sperm penetrate the egg. These enzymes are collectively referred to as sperm lysins.
- **Match**: Acrosome → (i) Sperm lysins

3. **Graafian Follicle**:
- The Graafian follicle is a mature ovarian follicle that produces estrogen. Estrogen plays a crucial role in the menstrual cycle and in preparing the body for ovulation.
- **Match**: Graafian Follicle → (ii) Estrogen

4. **Parturition**:
- Parturition refers to the process of giving birth. The hormone relaxin is important during this process as it helps to relax the pelvic muscles, facilitating childbirth.
- **Match**: Parturition → (iii) Relaxin

### Final Matches:
- Hypothalamus → (iv) Testosterone
- Acrosome → (i) Sperm lysins
- Graafian Follicle → (ii) Estrogen
- Parturition → (iii) Relaxin

### Summary of Matches:
1. Hypothalamus - (iv) Testosterone
2. Acrosome - (i) Sperm lysins
3. Graafian Follicle - (ii) Estrogen
4. Parturition - (iii) Relaxin

### Correct Option:
Based on the matches, the correct option from the codes given would be option 4.
