|Why not option A?|
|Abhishek Singh said: (Apr 2, 2017)|
|It's option A.|

|Please explain. Why not option A is correct?|
|Rohit said: (Aug 31, 2017)|
|Yes, Options D is right.|
|Dhaval Vaghasiya said: (Jan 4, 2018)|
|RcosΔ/2 = length between the midpoint of long chord and center of the curve.
So, option D is right.

|Option D is correct. Considering the rigth angle on the center of the cord, then apply trigonometric functions.|

|Length of the chord - diameter multiply by the half degree of the sine.
= D x sin angle/2
= 2R x sine θ/2
