Show answer & explanation

Correct answer: A

Correct matching:

  • Disk scheduling → Shortest Seek Time: SSTF selects the disk request with the shortest seek time from the current head position.

  • CPU scheduling → Shortest Job First: SJF selects the waiting process with the smallest burst time.

  • Page replacement → Least Recently Used: LRU replaces the page that has not been used for the longest time.

  • Deadlock → Banker’s Algorithm: Banker’s Algorithm checks whether resource allocation keeps the system in a safe state.

Final answer: 1 – iii, 2 – i, 3 – iv, 4 – ii
