Solution

The correct option is D $J / K$
The amount of heat required to raise the temperature of the whole body through $1^{o}$ or $1 K$ , is called one heat capacity or thermal capacity and is given by:
heat capacity $= m c$
where, $c =$ specific heat of body (SI unit $= J k g^{- 1} K^{- 1}$ )
$m =$ mass of the body (SI unit $= k g$ )
now, heat capacity $= k g \times J k g^{- 1} K^{- 1} = J K^{- 1}$ , this is the SI unit of heat capacity.
