A Correct answer
Explanation

The code fails to compile due to two errors: (1) 'class B extends class A' - should be 'class B extends A' without the word 'class' before A, and (2) class A has a private constructor, so it cannot be instantiated in main(). The code has multiple compilation errors preventing it from running.
