Which of the following statement($s$) is(are) correct?
$(A)$ The magnitude of the total work done in the process $A \rightarrow B \rightarrow C$ is $144 kJ$.
$(B)$ The magnitude of the work done in the process $B \rightarrow C$ is $84 kJ$.
$(C)$ The magnitude of the work done in the process $A \rightarrow B$ is $60 kJ$.
$(D)$ The magnitude of the work done in the process $C \rightarrow A$ is zero.

$(A)$ the process during the path $\mathrm{A} \rightarrow \mathrm{B}$ is isothermal
$(B)$ heat flows out of the gas during the path $\mathrm{B} \rightarrow \mathrm{C} \rightarrow \mathrm{D}$
$(C)$ work done during the path $\mathrm{A} \rightarrow \mathrm{B} \rightarrow \mathrm{C}$ is zero
$(D)$ positive work is done by the gas in the cycle $ABCDA$
