Solution

The correct option is A
Streamlining
Lubrication, polishing and ball bearings are effective in reducing friction between two solids but not very effective in case of fluid friction.

Fluid friction (Air drag) can be minimised by giving suitable shapes to bodies moving in fluids. Such shapes are called streamlined shapes.
