To determine the time complexity of a program to reverse a linked list, we need to analyze the steps involved in the process.

1. Traverse the linked list: In order to reverse the list, we need to traverse through each node of the linked list. This requires visiting each node once.

2. Reverse the pointers: During the traversal, we need to reverse the pointers of each node to change the direction of the list. This operation takes constant time for each node.

Therefore, the time complexity of reversing a linked list is O(n), where n is the number of nodes in the list. This means that the time taken to reverse the list increases linearly with the size of the list.

Hence, the correct answer is O(n).
