The correct option is grounded in Article 253 of the Indian Constitution, which empowers Parliament to enact laws for the implementation of international treaties, agreements, or conventions. This authority exists without requiring the consent of individual states, reflecting the central government's role in ensuring India's international obligations are met uniformly across the country. Such provisions facilitate a cohesive legal framework necessary for foreign relations, reinforcing India's sovereign commitments while maintaining the primacy of Parliament in matters affecting the nation as a whole.
