Question

• B. Response ratio
• C. Deadline
• D. First come first serve

Answer 1

Answer:

B. Response ratio

Pre-emptive scheduling techniques include those like shortest remaining time and round-robin. Response ratio, while not a typical pre-emptive method, is related to scheduling criteria where jobs are prioritized based on their response ratios, which can be adapted into a pre-emptive context.
