(D) The unit of $K_{c}$ is given by $(mol \ L^{-1})^{\Delta n}$,where $\Delta n$ is the change in the number of moles of gaseous products and reactants.For the unit to be $mol \ L^{-1}$,$\Delta n$ must be equal to $1$.For option $D$: $PCl_{5(g)} \rightleftharpoons PCl_{3(g)} + Cl_{2(g)}$,$\Delta n = (1 + 1) - 1 = 1$.Thus,the unit of $K_{c}$ for this reaction is $(mol \ L^{-1})^1 = mol \ L^{-1}$.
