Which of the following statements is correct? Select one: a. Most front-wheel drive vehicles use a positive scrub radius. b. Scrub radius is a measure of how small a circle the vehicle can turn in when the steering wheel is turned to the limit. c. Ideally, the thrust line and the vehicle's geometric centerline should line up closely. d. A setback issue in the rear will pull toward the side with the maximum setback.

The correct answer is:<br />c. Ideally, the thrust line and the vehicle's geometric centerline should line up closely.<br /><br />Explanation:<br />- Option a is incorrect because most front-wheel drive vehicles use a negative scrub radius.<br />- Option b is incorrect because scrub radius is a measure of how much the tire scrub (or slide) when the steering wheel is turned to the limit.<br />- Option c is correct because when the thrust line (the direction the drive wheels push) and the vehicle's geometric centerline (the imaginary line that runs through the center of the vehicle) are aligned closely, it results in better handling and stability.<br />- Option d is incorrect because a setback issue in the rear will pull toward the side with the minimum setback, not the maximum.
