Which one is the correct option for the two different thermodynamic processes?

(2)

Option (a) is wrong; since in adiabatic

process $V \neq$ constant.

Option (b) is wrong, since in isothermal process

$T=$ constant

Option (c) $\backslash \&$

(d) matches isothermes $\backslash \&$

adiabatic formula:

constant $\backslash \& \frac{\mathrm{T}^{\gamma}}{\mathrm{p}^{\gamma-1}}=$ constant
