Assertion (A): Bonded suspension bushes are tightened at normal ride height.

Reason (R): The bush rubber is bonded to its inner and outer sleeves.

Select the correct answer from the options below.

  • A.Both A and R are true, and R is the correct explanation of A
  • B.Both A and R are true, but R is not the correct explanation of A
  • C.A is true but R is false
  • D.A is false but R is true

Answer: A

Because the rubber cannot slip on its sleeves, whatever angle the arm is at when the bolt is tightened becomes the bush's neutral position for life. Clamping at full droop leaves it permanently twisted, so the reason explains the instruction exactly. The shared behaviour explains why these belong together and the differences explain why both exist. Tracing the requirement back to the physical constraint that produces it makes the answer follow.
