Question

I had attempted a test on Punctuation, English Grammar . The question was : 'Which of the following sentences in incorrect? 1. He asked me why I was late for the class . 2. He asked me why I was late for the class ? ' I pressed option 2 but it was showing that the correct answer would be option 1. But as per I have learnt from school , a sentence can end with a question mark if it starts with a 'w' interrogative word like when or was or where . So , can you please explain what should be the correct answer and why ?

Answer 1

Actually i also agree with your answer, which is grammatically absolutely correct.
