e is directly proportional to v^2 and also inversely proportional to R.

e is the rate of superelevation.
h = e * B is the super elevation (which is proportional to width).
h = e * B is the super elevation (which is proportional to width).

Super-elevation = v^2/2r.
Hence, it should be directly proportional to square root of velocity and inversely proportional to the radius of curvature.

directly proportional to velocity and width.
Inversely to the radius.
It seems wrong in acceleration.

According to me, It's directly proportional to the SQUARE of velocity.

Directly proportional = width and sq of speed (not velocity).
Inversely = acceleration due to gravity and radius of the curve.

E = eB.
Here in above relation;
e= Rate of super elevation,
And E = total super elevation.
Therefore total super elevation is directly proportional to width B.
But rate of super-elevation that is e is not proportional to width as the product of e and B is equal to E.
So, option A is incorrect.

V^2/gr.
v-velocity of the vehicle,
g-gravitational force,
r-radius of the curve so right answer is option A.
