When should you use an ArrayList over a LinkedList?

For frequently updating elements in the middle of the list
For rare insertions and deletions
For frequent random access
When memory usage is a concern

The correct answer is: For frequent random access

An ArrayList is more efficient for frequent random access because it stores data in a continuous block in memory, allowing for faster index-based retrieval. A LinkedList, on the other hand, stores data in nodes that are linked together, making it more efficient for insertions and deletions at the beginning or end of the list. Therefore, options A and B are incorrect. Option D is also incorrect because both ArrayList and LinkedList have similar memory usage. Therefore, the correct answer is C.
