The correct answer is option 1, Jawaharlal Nehru. After India gained independence from British rule in 1947, Jawaharlal Nehru became the first Prime Minister of India. Prior to that, he served as the Foreign Minister of India from 1947 to 1964.

Option 2, Gulzari Lai Nanda, was an Indian politician who served as the acting Prime Minister of India twice, but he did not hold the position of Foreign Minister.

Option 3, Lai Bahadur Shastri, was the second Prime Minister of India, succeeding Jawaharlal Nehru. However, he also did not serve as the Foreign Minister.

Option 4, John Mathai, was an Indian economist and politician, but he did not hold the position of Foreign Minister either.

Therefore, the correct answer is Jawaharlal Nehru.
