Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R

Assertion A: The AVL trees are more balanced as compared to Red Black trees, but they may cause more rotations during insertion and deletion

Reason R: A Red Black tree with n nodes has height that is greater than 2 log₂(n + 1) and the AVL tree with n nodes has height less than logφ(√5(n + 2)) − 2

In the light of the above statements, choose the correct answer

  1. A.

    Both A and R are true and R is the correct explanation of A

  2. B.

    Both A and R are true but R is not the correct explanation of A

  3. C.

    A is true but R is false

  4. D.

    A is false but R is true

Show answer & explanation

Correct answer: C

Assertion A is correct because AVL trees maintain stricter balance than Red-Black trees, leading to more rotations during updates. Reason R is incorrect because the height of a Red-Black tree with n nodes is at most 2 log₂(n + 1), not greater. Thus, A is true and R is false.
