Solution

The correct option is B $J K^{- 1}$
The heat capacity of a defined system is the amount of heat needed to
raise the system's temperature by one degree. It is expressed in units of thermal energy per degree temperature.
$q = C \times t$
$C = \frac{q}{△ t}$
here, $C =$ heat capacity
$q =$ heat required
$△ t = t_{1} - t_{2}$
so,The S.I. unit of heat capacity is $J K^{- 1}$
