A-1, B-2, C-3, D-4 Explanation: A. Monitor Abstraction -> 1. High-level construct providing safe, implicit mutual exclusion Monitor ek high-level synchronization construct hai jo programmer ko implicit (automatically) mutual exclusion provide karta hai. B. Condition Variable -> 2. Programmer-defined sync variable inside a monitor (x.wait(), x.signal()) Condition variables ( x.wait() , x.signal() ) monitor ke andar synchronization ke liye programmer-defined variables hote hain. C. Signal and Wait -> 3. Signaler blocks until the awakened process leaves the monitor Signal and Wait semantics me jab koi process signal bhejta hai, to wo tab tak block ho jata hai jab tak awakened process monitor se bahar na nikal jaye. D. Signal and Continue -> 4. Signaler keeps executing; awakened process waits to re-enter Signal and Continue
