I don't know about the correctness of my opinion by the expression for surface roughness is something like this,
H (surface roughness) = (feed rate) /[cot (principal cutting edge angle) + cot (auxiliary cutting edge angle)].
This expression is valid when the nose radius is negligible.
If nose radius has appreciable value then,
H= (feed) /[8x (nose radius) ^2].
So in both, the cases feed rate (option C in the given question) would be the correct answer I think.
