P-V Diagrams & Cyclic Processes

The $P\text{-}V$ diagram for an ideal gas in a piston cylinder assembly undergoing a thermodynamic process is shown in the figure. The process is

Show answer and solution

Answer: (d)

The graph is a horizontal line on the $P$ - $V$ diagram: $P$ stays constant while $V$ increases.
Constant pressure process is isobaric.
So the answer is (d) isobaric.
