For one complete cycle of a thermodynamic process on a gas as shown in the $P-V$ diagram,which of the following is correct?

Three moles of an ideal monoatomic gas undergo a cyclic process as shown in the figure. The temperatures of the gas in different states marked as $1, 2, 3$ and $4$ are $400 \ K, 700 \ K, 2500 \ K$ and $1100 \ K$ respectively. The work done by the gas during the process $1-2-3-4-1$ is (universal gas constant is $R$): (in $R$)

$A$ cyclic process $ABCD$ is shown in the given $P-V$ diagram. In the following answer, the one that represents the same process as in the $P-T$ diagram is:

In the cyclic process shown on the $P-V$ diagram,the magnitude of the work done is
