Thread synchronization is a method to ensure that multiple threads can run without interfering with each other.

Here's a step-by-step explanation:

1. Thread synchronization is defined as a mechanism which ensures that two or more concurrent threads do not simultaneously execute some particular program segment known as critical section.

2. Concurrent accesses to shared resource can lead to race condition.

3. Thread synchronization is defined as a mechanism which ensures that two or more concurrent threads do not simultaneously execute some particular program segment known as critical section.

4. Threads synchronization aid in the avoidance of concurrent thread interference and consistency problems.

5. Commonly used methods for thread synchronization in Java are:

   • Synchronized method
   • Synchronized block
   • Static synchronization
   • Inter-thread communication
   • Locking
   • Deadlock

So, the correct answer is c. A method to ensure that multiple threads can run without interfering with each other.
