Answer 2

Answer:

Explanation:

A) is the right answer because metals expand on heating and contrcts on cooling

so the size of metal rim is taken a bit of smaller size as when it is subjected to heat,it will expand and adheres firmly to the wooden wheel by increasing size.

so if the rim is taken as the same size of wooden wheel,then there would be no space for expansion.
