Solution

The correct option is A
Static friction > sliding friction > rolling friction.

When a body starts sliding, the contact points on its surface do not get enough time to lock into the other surface. So, sliding friction is slightly smaller than maximum static friction. It is always easier to roll than to slide a body over another. So, rolling friction is further smaller than sliding friction. Hence the correct order is: static friction > sliding friction > rolling friction.
