Choose the correct statement for processes A & B shown in figure.

Options

1. A$P{V}^{\gamma} = k$ for process $B$ and $PV = k$ for process $A$.
2. B$PV = k$ for process $B$ and $A$.
3. C$\dfrac{{P}^{\gamma - 1}}{{T}^{\gamma}} = k$ for process $B$ and $T = k$ for process $A$.
4. D$\dfrac{{T}^{\gamma}}{{P}^{\gamma - 1}} = k$ for process $A$ and $PV = k$ for process $B$.
