I’m not sure about C, seems like it could cause issues.

Totally agree with D, it’s the cleanest way to avoid leaks.

Wait, can you really delete a pointer twice? That's risky!

I think B is enough, no extra code needed.

I’m leaning towards option A, but I’m not confident. The double delete in option C seems risky too.

I practiced a similar question, and I feel like option B might be misleading. We definitely need some code to manage memory.

I'm not entirely sure, but I remember something about destructors needing to clean up resources. Maybe option C is correct?

I think option D is the right choice since it only deletes the pointer once, which should prevent memory leaks.

I think option D is the correct answer, but I want to make sure I'm not missing any edge cases or potential issues.

I'm a bit confused by the different options. I'll need to double-check my understanding of memory management in C++ to make the right choice here.

Okay, let me think this through step-by-step. The key is to identify the correct way to deallocate the memory for the 'ptr' object.

Hmm, this looks tricky. I'll need to carefully read through the code and options to make sure I understand what's causing the memory leak.

Hmm, this seems like a tricky one. I'll need to think through the key concepts around tasks and executors to figure this out.

This is a tricky one, but I think turning off the computer and rebooting from a clean system disk is the safest option.

Okay, let's see. I think the main things are not deleting the existing installation and making sure Alfresco starts up properly with the new version.

I think the mnemonic for the Enter key might be "{enter}", but I'm not completely sure.
