You may find this answer strange, but I assure you it is a true and valid answer to your question.

You see when you ask a question in the negative "Which of the following DID NOT" then almost anything is a true valid answer. Therefore when asking questions in future please try not to ask them in the negative and specify what "the following" are in the question.
