P-V Diagrams & Cyclic Processes

Which of the following graphs between pressure and volume of a gas correctly shows isochoric process in thermodynamics?

Show answer and solution

Answer: (d)

Isochoric process: volume stays constant, $V =$ constant.
On a $P$ - $V$ graph this is a vertical line (P changes, V fixed), which is graph (B).
So the answer is (d) (B).
