At valley curves is the correct answer.

I agree because this will make no effort the driver to cross whole curve as momentum gained in the first half journey will be equal to the lost in second half journey.

A gradient at which no tractive force is required to maintain constant speed by a vehicle is called floating gradient. Floating gradients are generally provided at summit curves. Correct answer is "C".
