Correct option is (a) True

For explanation: The viscosity of the lubricating must not be low. It also should not be too high. If it is too high then the liquid flow more faster and causes high or excessive friction. If it is low then the liquid moves very slowly and have low friction. Sufficient viscosity should be there to keep a liquid in a position.
