A-1, B-2, C-3, D-4 Explanation: A. synchronized Block -> 1. Automatically acquires an intrinsic lock on the target object Java me synchronized block target object par automatically intrinsic lock (monitor lock) acquire karta hai. B. wait() Method -> 2. Releases the object lock and moves the thread to the waiting queue wait() method object ke lock ko release kar deta hai aur current thread ko waiting queue me bheja jata hai. C. notify() Method -> 3. Wakes up a single thread waiting on the object's monitor notify() method object ke monitor par wait kar rahe kisi ek thread ko wake up karta hai. D. ReentrantLock -> 4. Advanced explicit lock offering fairness settings and try-lock modes ReentrantLock ek advanced explicit lock hai jo flexibility, fairness settings, aur tryLock() jaise modes provide karta hai.
