D Correct answer
Explanation

The code has a critical error: main is not declared static, so it's an instance method. Java requires public static void main(String[]) as the entry point. Since main() is not static, attempting to call it causes a runtime exception (NoSuchMethodException or similar). This tests understanding of Java's main method signature requirements.
