A system is taken from state a to state c by two paths adc and abc as shown in the figure. The internal energy at a is `U_a= 10 J`.Along the path adc the amount of heat absorbed `delta Q_1= 50 J` and the work obtained `delta W_1 = 20 J `whereas along the path abc the heat absorbed `delta Q_2 =36 J` The amount of work along the path abc is :
.

A

6 J

B

10J

C

12J

D
