If input data is incorrect but the CPU works correctly, what may the result be?

Correct answer: The result may be wrong because processing used incorrect data

The governing concept is the input-process-output principle: the processor follows its instructions and operates on the data it receives. If the input is inaccurate, correct execution can still produce an inaccurate output; this is often summarized as “garbage in, garbage out.” Option B is correct. A CPU does not automatically know the intended value, and incorrect input does not necessarily erase a hard disk or guarantee a correct answer.
