To answer this question, you need to understand the sequence of events that occur when a computer boots up.
Option A) System software - This option is incorrect because system software refers to a collection of software programs that manage and control the computer's hardware resources. System software is not the first program run on a computer during boot-up.
Option B) Operating system - This option is correct because the operating system is the first program that is loaded into the computer's memory when the computer boots up. The operating system controls the computer's hardware and provides a platform for other software programs to run.
Option C) System operations - This option is incorrect because "system operations" is not a commonly used term and does not accurately describe the first program run on a computer during boot-up.
Option D) None - This option is incorrect because there is always a program that runs first when a computer boots up, and that program is the operating system.
The correct answer is B) Operating system. This option is correct because the operating system is the first program run on a computer when it boots up.
