An Ideal Gas Undergoes the Process A→b→c→a Shown in the PV

An ideal gas undergoes the process a→b→c→a shown in the pV diagram.The thermal energy transferred to the gas through heating gas in process a→b is 546 J,while in process $b \rightarrow c$ the gas loses 62.0 J of thermal energy through heating.In process a→b there is - $310 \mathrm {~J}$ of work performed on the gas,while in process c→a 223 J of work is done on the gas.How much heat is gained by the gas in process c→a?

A) -397 J
B) -62 J
C) 223 J
D) 18 J
E) -236 J
