The correct answer is D.
According to the mythology, Sir Ector was the adoptive father of King Arthur. He did not t know the real identity of the child when Merlin brought him and he welcomed Arthur at this home. Moreover, Sir Ector had a son: Sir Kay. Sir Ector raised them together, as if both were his sons and the boys loved each other as real brothers too.
After having drawn the sword from the stone and proved himself as the rightful king of England, Arthur was named the monarch. Meanwhile, he never forgot about those who had cared for him until then. He named his brother Kay, the Seneschal of England and made Sir Ector the propiertor of broad lands within the country.
