A system is allowed to move from state A to B following path ACB by absorbing 80 J of heat energy. The work done by the system is 30 J.  The work done by the system in reaching state B from A is 10 J through path ADB. Which statements are correct? (i) Increase in internal energy from state A tc state B is 50 J. (ii) If path ADB is followed to reach state B, \[\Delta E=50J\]. (iii)  If work done by the system in path AB is 20J,the heat absorbed during path AB = 70 J. (iv)  The value \[{{E}_{C}}-{{E}_{A}}\]is equal to \[{{E}_{D}}-{{E}_{B}}\]. (v) Heat absorbed by the system to reach B from A through path ADD is 60 J.

A) \[\text{I,V}\]                    

B) \[\text{I,III,V}\]

C) \[\text{I, II, III, V}\]                        

D) \[\text{I,IV,V}\]
