Explanation: Control Process is a form of retaining short term memory. It is a process of way of keeping or losing information in short term memory.
Short term memory differs from long term memory, it is in our present consciousness while long term memory is stored, archived and can be retrieved after making an effort.
The control process used in the above question is rehearsal, a continuous repetition of information that we want to remember. It delays the loss of short term memory and can even help save information in long term memory.
