A Correct answer
Explanation

Steering mechanisms, such as the rack-and-pinion or Ackermann steering, use surface contact between components (gears, racks, shafts) which characterizes a lower pair. Lower pairs have surface contact while higher pairs have point or line contact, making steering mechanisms a clear example of lower pair kinematics.
