(C) The net work done by a gas in a closed cycle on a $P-V$ diagram is equal to the area enclosed by the cycle.To maximize the net work done,we need to choose two paths that enclose the largest possible area between them.In the given diagram,path $a$ is the topmost curve and path $f$ is the bottom-most curve that allows for a closed cycle (given the directions of the arrows).By choosing path $a$ and path $f$,the area enclosed between them is the largest among all possible combinations of paths shown.Therefore,the closed cycle formed by paths $a$ and $f$ results in the maximum net work done by the gas.

The $P-V$ diagram shows seven curved paths (connected by vertical paths) that can be followed by a gas. Which two of them should be parts of a closed cycle if the net work done by the gas is to be at its maximum value?
