(B) The given graph is a $V-P$ graph. In a $P-V$ diagram,the work done is the area under the curve. For a $V-P$ diagram,the work done is the area enclosed by the loop,but with a sign convention opposite to that of a $P-V$ diagram.In a $P-V$ diagram,a clockwise loop represents positive work,and an anticlockwise loop represents negative work.In this $V-P$ diagram,the smaller loop is anticlockwise (which corresponds to positive work in $V-P$ coordinates) and the larger loop is clockwise (which corresponds to negative work in $V-P$ coordinates).Since the area of the larger clockwise loop is greater than the area of the smaller anticlockwise loop,the net work done will be negative.

In the indicator diagram (shown in the figure),the net amount of work done will be
