A Correct answer
Explanation

The code creates a Thread with Runnable object A, names it 'good', and starts it. The run() method prints the current thread's name using Thread.currentThread().getName(), which returns 'good' since we explicitly set it with t.setName(). No compilation or runtime errors occur.
