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

A

$$PV^{\gamma} = k$$ for process $$B$$ and $$PV = k$$ for process $$A$$

B

$$PV = k$$ for process $$B$$ and $$A$$

C

$$\frac{P^{\gamma-1}}{T^{\gamma}} = k$$ for process $$B$$ and $$T = k$$ for process $$A$$

D

$$\frac{T^{\gamma}}{P^{\gamma-1}} = k$$ for process $$A$$ and $$PV = k$$ for process $$B$$
