-9 volts

see current in the circuit is 1 amp

now apply kvl from V₁ to ground and get the ans.

Well the answer given is correct.Can you elaborate this ? I did not get KVL from V1 to ground thing.I mean how can u do it when its not forming a loop.

kvl means apply a voltage path indicated and make voltage difference equal to v1(which is of rest of the circuit)
