Answer:
The correct answer to the following question will be Option B (ROM).
Step-by-step explanation:
Bootstrap is the programming which initializes the OS during initialization. The bootstrap loader creates small operator programs that connect and monitor the various computer hardware components.
ROM is Read-only memory, which will be used to hold a computer's start-up commands, also recognized as firmware.
No other method was used to help save system startup. ROM, then, is the right answer.
