Solution

The correct option is A Both assertion and reason are true and the reason is the correct explanation for the assertion.

If banking of roads is improper, then static friction $f_{s}$ will also come into picture to provide the necessary centripetal force.

And as we know, when friction comes into play, there will be wear and tear of the surfaces.

Thus, the reason explains the assertion.
