I think the answer is option A.
Minesh Rathore said:

Yes, the answer should be A.
Because hydraulic radius for pipe and square section is the same D/4. So, the ratio is 1.
Because hydraulic radius for pipe and square section is the same D/4. So, the ratio is 1.

Absolutely the answer is A.

Answer is 3/4 since the wetted perimeter in case of a square is 3d and not 4d.

Both hydraulic radius is not same.
Circular hydraulic radius = D/4 and
Square Hydraulic radius = 3/D.
So Ans is D.
Circular hydraulic radius = D/4 and
Square Hydraulic radius = 3/D.
So Ans is D.

D is the correct answer. I agree.

For circular pipe hydraulic mean depth = d/4.
For the square section of channel hydraulic mean depth=d/3.
Ratio of the circle to square= 3/4.
For the square section of channel hydraulic mean depth=d/3.
Ratio of the circle to square= 3/4.

It should be 4/3.
As the hydraulic radius of circle = d/3.
Hydraulic radius of square = d/4.
As the hydraulic radius of circle = d/3.
Hydraulic radius of square = d/4.
