Correct option is D
Article 7 of the UN Charter lists the principal organs of the United Nations, and the International Court of Justice is listed as one of these organs. Thus, the statement is partially correct, but the more accurate reference would be to mention Article 92, which specifically defines the role of the International Court of Justice in detail. The Reason (R) is correct in stating that there are 15 judges, but they are elected by both the UN General Assembly and the Security Council independently, not just by the Security Council. Therefore, (A) is false, and (R) is true.
