Given: What is the result?

The correct answer is A. Compilation fails. The compilation fails as SampleClassA and SampleClassB cannot override SampleClass because the return type of SampleClass is int, while the return type of SampleClassA and SampleClassB is long. Note: If all three classes had the same return type the output would be: Hash is : 111
