The correct answer is E. None of the above.
The maximum size of a swap partition is not limited by the kernel version. It is limited by the amount of physical memory on the system. The swap partition can be up to the size of the physical memory, but it is not required to be.
A swap partition is a section of a hard disk that is used to store data that is not currently being used by the system. This can include data that has been loaded into memory but is not currently being accessed, as well as data that has been swapped out to make room for new data.
The size of the swap partition should be at least equal to the amount of physical memory on the system. This will ensure that there is always enough space to store data that needs to be swapped out. However, it is also possible to create a swap partition that is larger than the amount of physical memory. This can be useful if you want to be able to run multiple programs at the same time without running out of memory.
If you are not sure how much swap space you need, it is always best to err on the side of caution and create a swap partition that is larger than the amount of physical memory on your system.
