I think the answer is 0.25d, not 0.95.

A is the correct answer.

I think the most economical section is when descharege is increase and hydraulic radius is increase but wetted peremeter is decrese because hydraulic radius=area /wetted permeter to increase radius we must increase diameter so A, B are corect Q=1/N R^2/3S^1/2.
R =area /peremeter.
