What can prevent a finally block from executing?

  1. An uncaught exception in the try block

  2. A return statement in the try block

  3. A call to System.exit()

  4. Nothing can prevent the finally block from executing

The correct answer is: A call to System.exit()

A call to System.exit() is an explicit way of terminating the entire Java program and therefore prevents any code, including the finally block, from executing after it. Options A and B may lead to the catch block being executed, but the finally block will still run. Option D is incorrect because the finally block will execute unless the program is terminated, which can be done through a call to System.exit().
