Solution

The correct option is B Infinity
The molar heat capacity is the amount of heat required to increase the temperature of one mole of a substance by one degree.If some finite heat is supplied, the ice would melt to water, without any change in temperature. So the molar heat capacity = $\frac{H e a t s u p p l i e d}{0}$ = Infinity.
