The Graph Shows the Temperature of a 1

The graph shows the temperature of a 1.0-g sample of material as heat is added to it. The material is initially a solid at 10^oC. The pressure remains constant, and there is no chemical change. The specific heat of the liquid phase is

A) 0.84 cal/g · C^o.
B) 0.25 cal/g · C^o.
C) 1.6 cal/g · C^o.
D) 1.7 cal/g · C^o.
E) None of these is correct.
