Question

Which of the following graphs between pressure and volume correctly shows isochoric change? (A)  (B)  (C)  (D)

Isochoric process takes place in a system at constant volume, hence P-V graph is a straight line parallel to pressure axis represented by option [c].
Isobaric process takes place at constant pressure.
The P-V graph is a straight line parallel to V axis represented by option [b].
