What is the intended purpose of an anti-lock braking system (ABS)?

Answer: B — To prevent wheel lock-up during braking

The purpose of an anti-lock braking system (ABS) is to prevent wheel lock-up during braking. When a driver applies the brakes in a vehicle without ABS, especially in slippery conditions, the wheels can lock up, causing a loss of steering control. This can result in a skid, making it difficult for the driver to maintain control of the vehicle. ABS works by automatically modulating brake pressure to prevent the wheels from locking. This allows the driver to maintain steering control even during hard braking, enhancing safety and stability. While the other options relate to different vehicle functionalities, they do not align with the primary function of ABS. Enhancing acceleration, reducing fuel consumption, or improving steering responsiveness are not the main purposes of an ABS. Instead, the focus of ABS technology is specifically on braking performance and maintaining control during emergency stops.
