Correct option is
D
Friction can be reduced to zero
We can reduce the friction between two surface by polishing the surface, by converting the shape of body like rolling friction is less than sliding friction so we can use tyres in place of sliding the object.
Friction can be minimized but cannot reduced to zero.
Option D is not true.
