Pakistan & France agreed on 31 July 1951 to initiate

In the nascent years of its independence, Pakistan prioritized establishing formal diplomatic ties with nations worldwide to secure its international standing and foster bilateral relations. The agreement with France in 1951 was a significant step in this direction.

• Correct Option A: Embassy Service is accurate. On July 31, 1951, Pakistan and France formally agreed to exchange diplomatic missions, specifically establishing embassies in each other's capitals. This foundational step allowed for direct communication, representation, and the development of all aspects of bilateral relations.
• Option B: Nuclear Deal is incorrect; discussions or agreements on nuclear cooperation between Pakistan and France occurred much later in their relationship, not in 1951.
• Option C: Economic Ties, while a crucial component of international relations, typically develop after the establishment of formal diplomatic channels like embassies, rather than being the initial agreement itself.
• Option D: None is incorrect as 'Embassy Service' correctly identifies the historical agreement.
