Which upgrade involves shutting down the old MySQL version and replacing the old binaries?

This question is about how we update MySQL. Imagine you have an old version of MySQL, like a dusty old computer. We need to upgrade to a newer, faster version.
There are different ways to upgrade, and this question asks about the type where we completely replace the old files (like replacing the old computer with a new one).
Think of it like this:
* Option A: Inplace: This is like fixing the old computer. We change some parts, but the main computer stays the same.
* Option B: Logical: This is like adding a new program to the old computer, we don't replace the whole thing.
* Option C: Illogical: This doesn't make sense in this context.
* Option D: System: This is like replacing the whole computer with a brand new one. We shut down the old one and install the new one.

So the answer is Option D: System. This method involves shutting down the old MySQL and replacing the old files with the new ones.
