I think it's B. NS^2/8H.
And H=0.75m.
And H=0.75m.

Length of valley curve formula is 0.38*√ nv^2.
How this has come? Please explain.

Headlight sight distance means stopping sight distance so answer is Ns^2/4.4.

For valley curves;
L= NS^2÷(1.5+0.035S) ; L>S.
L = 2S - N/(1.5+0.035S); L<S.
L= NS^2÷(1.5+0.035S) ; L>S.
L = 2S - N/(1.5+0.035S); L<S.
