Option C. In King Arthur's Knights, Sir Mordred and Sir Agravain were motivated to plot against Sir Lancelot as they both wanted the kingdom fro themselves.
Explanation:
Sir Mordred was King Arthur's son and nephew, from an intimate relationship King Arthur had with his step-sister Morgause, when he did not know they were related. In order to prevent his incestuous affair to become public, King Arthur ordered that every kid born on May st, as Mordred was, must be killed. But Mordred survived, and he knew that if he managed to kill King Arthur he would be the lawful heir to the throne. Mordred plans the downfall of King Arthur with the help of Sir Agravain, who was King Arthur's nephew. They both participate in the plot against the king as they both were rightful heirs and wanted the kingdom to themselves and King Arthur out of the picture and the round table.
