- Dipping ice in hot water
- Freezing of water

The Correct Option is C
Solution and Explanation
Step 1: Understand the term:
In an ice plant, water freezes inside metal cans kept in a cold brine tank. The ice sticks tightly to the walls of each can.
Thawing is the step that loosens this ice block so it can be taken out.
Step 2: See how thawing is done:
The ice cans are lifted out of the brine tank with a crane.
They are then dipped for a short time in a tank of warm or hot water.
The outer layer of ice melts, and the block slips out of the can easily.
Step 3: Check option (A) and (B):
Cleaning of ice is washing the surface of a block. It does not free the block from the can.
Breaking of ice would crush the block. A thawed block is taken out whole, so (B) is wrong.
Step 4: Check option (D):
Freezing of water is the opposite process. It forms ice, while thawing releases ice that is already formed. So (D) is wrong.
Final Answer:
Thawing means dipping the ice cans in hot water so the ice block comes out. This is option (C).
