The answer is A. He informed others that he had received a revelation from God.

 When Muhammad was 40 years old, he was commanded by God, by means of Gabriel his angel, to speak out His Unity to the followers and polytheists of the world, and to convey the peace message to the humankind. In reply to God’s command from Heaven, he made the significant program known as Islam which changed the purpose of manhood endlessly.
