Options

A. a-3,b-4,c-1,d-5,e-2
B. a-3,b-4,c-1,d-5,e-2
C. a-4,b-3,c-5,d-2,e-1
D. a-3,b-4,c-5,d-2,e-1

Answer

To solve the question, we need to match the hormones from Column I with their respective functions from Column II. Let's go through each hormone step by step:

### Step 1: Identify the Hormones and Their Functions
We have the following hormones in Column I:
- a. LH (Luteinizing Hormone)
- b. FSH (Follicle Stimulating Hormone)
- c. MSH (Melanocyte Stimulating Hormone)
- d. Oxytocin
- e. Estrogen

### Step 2: Match LH
**LH (Luteinizing Hormone)**:
- Function: It is responsible for ovulation in females and stimulates testosterone production in males.
- **Match**: 4. Ovulation

### Step 3: Match FSH
**FSH (Follicle Stimulating Hormone)**:
- Function: It stimulates the growth of ovarian follicles in females and is involved in spermatogenesis in males.
- **Match**: 3. Spermatogenesis

### Step 4: Match MSH
**MSH (Melanocyte Stimulating Hormone)**:
- Function: It regulates the pigmentation of the skin by acting on melanocytes.
- **Match**: 5. Pigmentation of skin

### Step 5: Match Oxytocin
**Oxytocin**:
- Function: It stimulates smooth muscle contraction, particularly during childbirth and helps in milk ejection from mammary glands.
- **Match**: 2. Milk ejection

### Step 6: Match Estrogen
**Estrogen**:
- Function: It is involved in the regulation of the menstrual cycle and increases the strength and tone of uterine muscles.
- **Match**: 1. Smooth muscle contraction

### Final Matches:
- a. LH → 4. Ovulation
- b. FSH → 3. Spermatogenesis
- c. MSH → 5. Pigmentation of skin
- d. Oxytocin → 2. Milk ejection
- e. Estrogen → 1. Smooth muscle contraction

### Conclusion:
The correct combination from the options given is:
- a - 4
- b - 3
- c - 5
- d - 2
- e - 1
