A toy car released with the same initial speed will travel farthest on
$(a)$. muddy surface
$(b)$. polished marble surface
$(c)$. cemented surface
$(d)$. brick surface

A polished marble surface is smoother than a muddy, brick, or cemented surface. So, a polished marble surface will offer the least friction to the toy car. Therefore, a toy car released with the same initial speed will travel farthest on a polished marble surface.

So, option $(b)$ is correct.
