Choose the correct statement for processes A & B shown in figure.
$P V=k$ for process $B$ and $A$.
$\frac{P^{\gamma-1}}{T^\gamma}=k$ for process $B$ and $T=k$ for process $A$.
$\frac{T^\gamma}{P^{\gamma-1}}=k$ for process $A$ and $P V=k$ for process $B$.
$P V^{\prime}=k$ for process $B$ and $P V=k$ for process $A$.
