Please explain. Why not option A is correct? |

Yes, Options D is right. |

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 |
