What is a possible effect of increasing a process priority in an operating system?

Correct answer: The process may receive more central processing time

The governing concept is operating-system scheduling. The scheduler decides which ready process receives CPU time, and a higher priority can make a process more likely to be selected sooner or more often, depending on the scheduling policy. Thus option A is correct, but it does not create extra storage or change physical hardware. Giving one process preference can also delay lower-priority tasks, so priorities should be changed carefully.
