The correct answer is D: They all share a common father in Abraham
Abraham is the shared father of Jews, Christians, and Muslims. Muslims believe that they have official line of the covenant with Abraham descends to the Arabs and Mohammed through Ishmael, the first-born son. Judaism is the unwilling parent of both Christianity and Islam. The three western religions are all derived from"the God of Abraham." In this sense, they have "the same God." But they passionately disagree with each other about how God's self-revelation is interpreted.
Christianity sees itself as the development and fulfillment of God's covenant with Abraham. Judaism sees Christianity as a corruption of Judaism. Islam sees itself as the reform, development, and fulfillment of Judaism and Christianity. Both Jews and Christians see Islam as a corruption of their traditions.
