Correct option is C
Article 38(1) of the Statute of the International Court of Justice recognizes:
· International conventions (treaties),
· International custom,
· General principles of law recognized by civilized nations,
· Judicial decisions and teachings of the most highly qualified publicists (as subsidiary means). "Equity and good conscience" is not listed as a primary source but may be considered under specific contexts.
Information Booster: The ICJ may apply equity if both parties agree, under Article 38(2), but it is not an independent source in 38(1).
