Correct Answer: Option A

Explanation

In simple harmonic motion (SHM), the acceleration is maximum at the extreme points (maximum displacement) of the motion. These points are where the restoring force is strongest, leading to the highest acceleration. Therefore, the correct answer is 'is maximum at the extreme ends. although option D is also true.
