This feature allows the vehicle to be set at a certain speed so that the motorist does not have to brake or accelerate to maintain a pre-selected speed: a) Anti-Lock Brakes b) Airbags c) Cruise Control d) Crumple Zones

## Step 1<br />The problem is asking us to identify a feature in vehicles that allows the driver to set a certain speed so that the motorist does not have to brake or accelerate to maintain a pre-selected speed. <br /><br />## Step 2<br />Let's analyze each option:<br />- Anti-Lock Brakes: This system prevents the wheels from locking up during braking, which helps the driver maintain steering control. However, it does not automatically set a speed for the vehicle.<br />- Airbags: This is a safety feature that inflates rapidly when a collision is detected, providing a cushioning effect to protect the occupants. It does not control the speed of the vehicle.<br />- Cruise Control: This feature allows the driver to set a certain speed for the vehicle, and the vehicle will automatically maintain that speed. This matches the description given in the problem.<br />- Crumple Zones: These are areas of a vehicle that are designed to deform in a collision, absorbing the impact and protecting the occupants. They do not control the speed of the vehicle.
