l think the option D is the right.
m = d/4 in circular.
m = d/4 in circular.

Correct answer is D/4.

It's for diameter. In this case, the radius is D.

D/2 is the right answer here.
In this question, the radius is indicated by 'D', so don't take it as a diameter. Hydraulic mean radius is defined by the ratio of Area by the perimeter, if you put the right relation in between, you will definitely see the answer comes to D/2.

Actually it is irrigation canal having triangular sides and circular bottom and for such canal:-
A = D"2 ( @ + cot@ )...........(1).
P = 2D ( @ + cot@ )..................(2).
therefore R = A/P = (1)/(2) = D/2.
So option B is correct
A = D"2 ( @ + cot@ )...........(1).
P = 2D ( @ + cot@ )..................(2).
therefore R = A/P = (1)/(2) = D/2.
So option B is correct
(1)
