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 $2\log_2(n+1)$ and the AVL tree with n nodes has height less than $\log_\phi(\sqrt{5}(n+2))-2$ where $\phi$ is golden ratio.

In the light of the above statements, choose the correct answer from the options given below.
