The correct answer is: A. 83
A swap partition is a partition on a hard disk that is used to store data that is not currently being used by the operating system. This can include data that is in memory but is not currently being accessed, as well as data that has been written to disk but is not yet being used by the operating system.
When the operating system needs more memory, it can swap data from memory to the swap partition. This frees up memory that can be used for other tasks. When the operating system needs to access data that is stored on the swap partition, it can swap data from the swap partition back to memory.
To create a swap partition, you need to use a partitioning tool such as fdisk. When you create a swap partition, you need to specify the partition’s system ID type. The system ID type for a swap partition is 83.
The other options are incorrect because they are not the system ID type for a swap partition. Option B, 82, is the system ID type for a Linux swap partition. Option C, 5, is the system ID type for an extended partition. Option D, 4, is the system ID type for a primary partition.
