The figure below shows the variation of specific heat capacity (C) of a solid as a function of temperature (T). The temperature is increased continuously from 0 to 500 K at a constant rate. Ignoring any volume change, the following statement(s)is (are) correct to a reasonable approximation.

A

the rate at which heat is absorbed in the range 0-100 K varies linearly with temperature T.

B

heat absorbed in increasing the temperature from 0-100 K is less than the heat required for increasing the temperature from 400-500 K.

C

there is no changein the rate of heat absorption in the range 400-500 K.

D

the rate of heat absorption increases in the range 200-300 K.
