B Correct answer
Explanation

The mkswap command initializes a file or partition to be used as swap space by setting up the swap header and metadata. After mkswap, swapon enables the swap device. Option A enables existing swap but doesn't create it. Option C creates a device node but doesn't initialize swap format. Swap creation is definitely possible.
