The Giza Pyramid Complex consists of three main pyramids: the Great Pyramid of Khufu (also known as Cheops), the Pyramid of Khafre (Chephren), and the Pyramid of Menkaure (Mycerinus). Option B 'Khafu' is an incorrect spelling - the correct name is Khafre. These three pyramids were built as tombs for pharaohs during the Fourth Dynasty of the Old Kingdom.
