$ \log P=\gamma \log \mathrm{V} \Rightarrow \mathrm{P}=\mathrm{V}^\gamma,(\gamma>1) $

$ P V^{-\gamma}=\text { Constant } $

$ C_A=C_V+\frac{R}{1+\gamma} \ldots . \text { (i) }$

Likewise for process $\mathrm{B} \rightarrow P V^{-1}=$ $Cons$ $\tan t$

$C_B$ $ =C_v+\frac{R}{1+1} $

$C_B$ $ =C_v+\frac{R}{2} $ $.............(ii)$

$C_P$ $=C_v+R$       $...........(iii)$

By $(i)$, $(ii)$ & $(iii)$ $C_P>C_B>C_A>C_v$ [No answer matching]
