What is the role of a vehicle's suspension system?

The suspension system of a vehicle plays a crucial role in supporting the weight of the vehicle and absorbing shocks from the road. This system comprises various components, including springs, shock absorbers, and control arms, all designed to provide a smooth and stable ride. By absorbing impacts from uneven surfaces, the suspension system enhances vehicle control, handling, and comfort for passengers.

Moreover, it maintains proper tire contact with the road, which is essential for safe driving and effective braking. The suspension system also helps manage body roll during cornering and provides stability when the vehicle is in motion. Hence, the primary function of the suspension is to balance the vehicle's weight distribution and mitigate the effects of road irregularities, making option B the correct choice.
