Answer:
Your answer is:-
Explanation:
When we provide wheels the total area in contact with the surface will decrease resulting in lesser net friction applied.
Lubricating will decrease the coefficient of friction which will in turn reduce the friction.
Streamlining is a design to provide with a form that presents very little resistance to a flow of air or water, increasing speed and ease of movement. This also decreases the friction.
Hence, all of these are correct.
The correct answer is option (D).
