Options

A. a(iii), b(iv), c(i), d(ii)
B. a(iii) ,b(i) ,c(iv) ,d(ii)
C. a(i) ,b(iii) ,c(ii) ,d(iv)
D. a(iii) ,b(ii) ,c(iv) ,d(i)

Answer

To solve the matching question, we will analyze each term in Column I and find the corresponding term in Column II.

### Step 1: Analyze Hibernation
- **Hibernation** is a state of inactivity and metabolic depression in endotherms during winter. It is commonly seen in animals that need to survive harsh winter conditions.
- **Match:** Polar bears (iii) are known for hibernation.

### Step 2: Analyze Aestivation
- **Aestivation** is similar to hibernation but occurs during hot and dry periods. It allows organisms to survive extreme heat.
- **Match:** Snails (i) undergo aestivation to avoid the harsh summer conditions.

### Step 3: Analyze Migration
- **Migration** refers to the seasonal movement of animals from one region to another for feeding or breeding.
- **Match:** Siberian cranes (iv) are well-known for their migratory behavior, traveling from Siberia to India.

### Step 4: Analyze Diapause
- **Diapause** is a period of suspended development in an organism, often in response to unfavorable environmental conditions.
- **Match:** Many zooplanktons (ii) can enter diapause to survive adverse conditions.

### Final Matches
- a. Hibernation - (iii) Polar bears
- b. Aestivation - (i) Snails
- c. Migration - (iv) Siberian cranes
- d. Diapause - (ii) Many zooplanktons

### Correct Option
The correct option is:
- A - iii
- B - i
- C - iv
- D - ii

### Summary of Matches
- a. Hibernation - (iii) Polar bears
- b. Aestivation - (i) Snails
- c. Migration - (iv) Siberian cranes
- d. Diapause - (ii) Many zooplanktons
