Multitasking is: Group of answer choices

A. the ability within a program which allows multiple parts or threads to run simultaneously.

B. the capability in an OS which supports a division of labor amoung all of the processing units.

C. a situation in which instructions and data from one area of memory overflow into memory allocated to another program.

D. the capability in an OS which allows two or more tasks, jobs, or processes to run simultaneously.

Option (A) and (D) are the correct suitable answer for the above question.

Explanation:

Multitasking is a concept in which multiple events are occurring at the same time. It is a processor power that can able to handle multiple tasks simultaneously in the same unit of time.

Practically, the events are not occurring at the same amount of time but it seems to the user that task is performing simultaneously because of processor switching. In processor switching, the processor switches the task one by one and performs them but it is so fast. Hence the user seems that the task is performing simultaneously.

Another option does not make any sense for the above question because--

Option b justify for the division of tasks not to do multiple tasks in a single unit of time.

Option C justifies the concept of memory allocation.
