A thermodynamic process is shown in Fig. The pressures and volumes corresponding to some points in the figure are
`P_(A) = 3 xx 10^(4) Pa` `V_(A) = 2 xx 10^(-3) m^(3)`
`P_(B) = 8 xx 10^(4) Pa` `V_(D) = 5 xx 10^(-3) m^(3)`
In the process `AB` `600 J` of heat is added to the system. The change in internal energy of the system in the process `AB` would be

Options

A. `560j`
B. `800j`
C. `600j`
D. `640j`
