Which method is used to start the execution of a thread in Java?  Question 1Answera. run()b. begin()c. start()d. launch()

The method used to start the execution of a thread in Java is c. start().

Here's a step-by-step explanation:

1. In Java, you create a thread by creating an object of the Thread class or by creating an object of any class that extends the Thread class.

2. These classes have a method called start(), which is used to begin the execution of the new thread.

3. When start() is called, the Java Virtual Machine calls the run() method of the Thread class to execute the new thread.

4. So, while the run() method contains the code that will be executed in the new thread, it's the start() method that begins the execution of the new thread.

Therefore, the correct answer is c. start().
