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

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

RcosΔ/2 = length between the midpoint of long chord and center of the curve.
So, option D is right.
So, option D is right.
