From the words lettered A to D, choose the word or group of words that best completes each of the following sentences.
I said John saw Mary yesterday......?

Answer Details

The correct option to complete the sentence is "didn't I." This is because "didn't I" is the appropriate tag question that matches the positive sentence structure "John saw Mary yesterday." A tag question is a short question added to the end of a statement to confirm or clarify the information provided in the statement. Therefore, the complete sentence with the appropriate tag question would be "I said John saw Mary yesterday, didn't I?"
