Which of the following will produce the maximum friction?
(a) rubbing of sand paper on glazed paper
(b) rubbing of sand paper on glass table top
(c) rubbing of sand paper on aluminium frame
(d) rubbing of sand paper on sand paper

The friction produced between surfaces of two objects will be maximum if both the surfaces are rough rather than between two rough-smooth or smooth-smooth surfaces.

So, rubbing of sandpaper on sandpaper will produce maximum friction.

So, option (d) is correct.
