What is the worst-case time complexity of quicksort?

Correct! Well done.

Incorrect.

The correct answer is C) O(n²)

C

Correct Answer

O(n²)

Explanation

Quicksort degrades to O(n²) when the pivot is always the smallest or largest element (e.g., sorted input with naive pivot selection). Randomized pivot reduces this risk.
