Prashanth_p@cchiI think, the Answer is B.
Explanation: Considering a and b to be 1(simple value).

Correct me if I am missing something.
if a=1 and b=1 then z=2
the equation gives 2
but option B gives 3 -

Apologies!!!!!!! I considered it to be (z + 2)/2.zaverimaybe you are not right
if a=1 and b=1 then z=2
the equation gives 2
but option B gives 3 -
