Solution

The correct option is B heat was used for changing ice at $0^{\circ} C$ to water at $0^{\circ} C$
The temperature does not rise for some time because heat was used for changing ice at $0^{\circ} C$ to water at $0^{\circ} C$ . When heat is given to solid ice, it first absorbs energy to convert into liquid water. After some time, when it converts into liquid water, temperature starts increasing.
