Which methods are utilized to control the access to an object in…

Answer: Synchronized methods

Explanation: Synchronized methods use an object's intrinsic lock (monitor) to ensure mutual exclusion so that only one thread can execute the synchronized code on that object at a time.

• How it works: A synchronized instance method acquires the instance's lock; a synchronized static method acquires the Class object's lock.

• Scoped locking: Use synchronized blocks to limit the locked region (for example, synchronized(this) or synchronized(someLock) { ... }) to reduce contention.

• Alternatives: Explicit lock implementations (for example, ReentrantLock from java.util.concurrent.locks) provide features like tryLock, interruptible acquisition, and fairness policies.

• Why the other terms are wrong: "Asynchronized methods" suggests asynchronous execution (not mutual exclusion); "Serialized methods" refers to object serialization, not concurrent access control; therefore those are not mechanisms for controlling access.

Key takeaway: Use synchronized methods/blocks or explicit locks to control access to shared objects in multi-threaded programs; choose the tool that fits your needs for scope and flexibility.
