P-V Diagrams & Cyclic Processes

Which one of the following p-V diagram is correct for an isochoric process:

Show answer and solution

Answer: (c)

For an isochoric process $V_i = V_f$ while pressure changes.
Graph III goes from $p_i$ to $p_f$ at the same $V_i$ (vertical line).
So the answer is (c) III.
