    Answer : Option C

    Explanation :

    IRC recommends Spiral or clothoid as the ideal transition curve due to following reasons:

    1. It satisfies that rate of change of centrifugal acceleration is constant i.e., Ls.R = constant. Where Ls = length of transition curve R = radius of curve.

    2. The calculation and field implementation of spiral curve is simple and easy.

    3. It enhances aesthetics also.
