Now, According to law of conservation of momentum we know that

Initial momentum = Final momentum

m1v1 +m2v2 = (m1 + m2)v’

i.e., Mv = (M+m)v’ 

⇒ v to the power of apostrophe equals M divided by left parenthesis M plus m right parenthesis cross times √ 2 g h

Hence, option 2 is correct among the following.
