Q1:

In an ideal transition curve, the radius of curvature

A is constant

B at any point is directly proportional to its distance from the point of commencement

C is inversely proportional to the radius of main curve

D is directly proportional to the radius of main curve

ANS:C - is inversely proportional to the radius of main curve

But it is mentioned that it is the ideal transition curve. The shape of ideal transition curve is spiral. So C is correct.
