The main architect of India's foreign policy was:

Jawaharlal Nehru

The correct answer is option (3) - Jawaharlal Nehru

The main architect of India's foreign policy was Jawaharlal Nehru.

The first Prime Minister, Jawaharlal Nehru played a crucial role in setting the national agenda. He was his own foreign minister. Thus both as the Prime Minister and the Foreign Minister, he exercised profound influence in the formulation and implementation of India’s foreign policy from 1946 to 1964. The three major objectives of Nehru’s foreign policy were to preserve the hard-earned sovereignty, protect territorial integrity, and promote rapid economic development. Nehru wished to achieve these objectives through the strategy of non-alignment. There were, of course, parties and groups in the country that believed that India should be more friendly with the bloc led by the US because that bloc claimed to be pro-democracy.
