20g stream at 100°C is passed through 15g ice at -12°C. The mass of water in in calorie metre will be nearly (specific heat of ice =0.5 cal/g°C, specific heat of water=1 cal/g°C latent heat of vaporisation 540 cal/g, latent heat of fusion=80 cal/g and neglect heat capacity of calorimeter )

Options

A. 20g water at 100°C
B. 25g water at 100°C
C. 18g water at 100°C
D. 15g water at 100°C
