Explanation

To solve the question, we need to match the items in Column A with their corresponding values in Column B. Let's go through each item step by step.

### Step-by-Step Solution:

1. **Specific Heat of Water (A)**:
- The specific heat of water is defined as the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius.
- The specific heat of water is **1 cal/g°C**.
- Therefore, A matches with **d** (1 cal/g°C).

2. **Latent Heat of Fusion of Ice (B)**:
- The latent heat of fusion is the amount of heat required to convert 1 gram of solid (ice) into liquid (water) at constant temperature.
- The latent heat of fusion of ice is **80 cal/g**.
- Therefore, B matches with **e** (80 cal/g).

3. **Latent Heat of Vaporization of Water (C)**:
- The latent heat of vaporization is the amount of heat required to convert 1 gram of liquid (water) into vapor at constant temperature.
- The latent heat of vaporization of water is **540 cal/g**.
- Therefore, C matches with **f** (540 cal/g).

4. **Temperature at which Melting of Ice Starts under Normal Atmospheric Pressure (D)**:
- Ice starts to melt at **0°C** under normal atmospheric pressure.
- Therefore, D matches with **b** (0°C).

5. **Temperature at which Boiling of Water Starts under Normal Atmospheric Pressure (E)**:
- Water starts to boil at **100°C** under normal atmospheric pressure.
- Therefore, E matches with **c** (100°C).

### Final Matches:
- A → d (Specific heat of water = 1 cal/g°C)
- B → e (Latent heat of fusion of ice = 80 cal/g)
- C → f (Latent heat of vaporization of water = 540 cal/g)
- D → b (Temperature at which melting of ice starts = 0°C)
- E → c (Temperature at which boiling of water starts = 100°C)
