A-2, B-1, C-4, D-3 Explanation: A. Prevention -> 1. Designs the system to eliminate at least one of the four Coffman conditions Deadlock Prevention strategy system ko aise design karti hai ki chaar Coffman conditions (Mutual Exclusion, Hold and Wait, No Preemption, Circular Wait) me se kam se kam ek condition ko completely eliminate kar diya jaye. B. Avoidance -> 2. Uses runtime checks (like Banker's) to ensure the system stays in a safe state Deadlock Avoidance strategy runtime checks (jaise Banker's Algorithm) ka use karti hai aur dynamic decision leti hai taaki system hamesha ek safe state me rahe. C. Detection & Recovery -> 3. Allows deadlocks to happen, detects them, and recovers by terminating processes Deadlock Detection & Recovery strategy system me deadlock hone deti hai, periodically use detect karti hai, aur p
