Mathc colum I with Column II and select the correct option from the given codes.
`{:("Column I","Column II"),("Oxytocin",(i)"Stimulates ovulation"),("Prolactin",(ii)"Implantation and maintnance of pregnancy"),("Lutensing",(iii)"Milk production in mammary glands"),("Progesterone",(iv)"Uterine contraction during labour"),(,(v)"Reabsorption of water by nephrons"):}`

Options

A. v,iv,i,ii
B. `iv,i,ii,iii
C. iv,iii,i,ii
D. v,iii,ii,i

Answer

To solve the problem of matching the hormones in Column I with their respective functions in Column II, we will analyze each hormone and its role step by step.

### Step-by-Step Solution:

1. **Oxytocin**:
- **Function**: Oxytocin is known as the contraction hormone. It plays a crucial role during childbirth by stimulating uterine contractions.
- **Match**: Therefore, Oxytocin corresponds to (iv) "Uterine contraction during labour".

2. **Prolactin**:
- **Function**: Prolactin is primarily responsible for stimulating milk production in mammary glands after childbirth.
- **Match**: Thus, Prolactin corresponds to (iii) "Milk production in mammary glands".

3. **Luteinizing Hormone (LH)**:
- **Function**: Luteinizing hormone is essential for triggering ovulation, which is the release of an egg from the ovary.
- **Match**: Hence, Luteinizing Hormone corresponds to (i) "Stimulates ovulation".

4. **Progesterone**:
- **Function**: Progesterone is crucial for maintaining pregnancy and is involved in the implantation of the embryo in the uterus.
- **Match**: Therefore, Progesterone corresponds to (ii) "Implantation and maintenance of pregnancy".

### Summary of Matches:
- Oxytocin → (iv) Uterine contraction during labour
- Prolactin → (iii) Milk production in mammary glands
- Luteinizing Hormone → (i) Stimulates ovulation
- Progesterone → (ii) Implantation and maintenance of pregnancy

### Final Matching:
- Oxytocin → (iv)
- Prolactin → (iii)
- Luteinizing → (i)
- Progesterone → (ii)

### Conclusion:
The correct option from the given codes is option 3.
