While driving straight ahead, a front-wheel-drive car pulls to the right. The most likely cause of this problem is:
a. More positive camber on the left front wheel compared to the right front wheel.
b. Sagged front springs and improper front wheel toe setting.
c. Less positive caster on the right front wheel compared to the left front wheel.
d. The SAI on the right front wheel is 1.5 degree more than the SAI on the left front wheel.
