The heat capacity of a body is dependent on

Heat capacity of a body is defined as the amount of heat required to raise its temperature by unity.

$C = \dfrac{\Delta Q}{\Delta T} = m c$

where $m$ is the mass of the body and $c$ is the specific heat capacity of the material.

Since specific heat capacity is a characteristic property of the material, the heat capacity of a body depends on its mass and the material it is made of.

It is independent of the heat supplied and the increase in temperature.
