D) All of these

Reason

friction can be minimised by using lubricants like oil and grease and by using ball bearing between machine parts .

dry talcum powder reduces friction slightly for certain materials against skin, but increases friction when it becomes wetted.

An air cushion is a cushion which is filled by air .

this is used in many ways. since it forms a separation with air , so definitely it reduces friction.
