The correct answer is A.
Take the example of water.
For water, freezing happens at 0℃. When you start cooling water, its temperature will go down till 0℃ and ice will start forming. The temperature will remain at 0℃ until all the water is converted to ice. The freezing is completed at 0℃.
When a piece of ice is kept in open, first its temperature will rise till 0℃ from subzero temperature.(sub zero temperature means minus temperature, like -5℃). Once it reaches 0℃, it will start MELTING. during melting, the temperature will remain constant at 0℃ until all ice is melted to water. So the melting process is completed at 0℃.
Thus both melting and freezing happens at 0℃.
