In the context of Colonial India, Shah Nawaz Khan, Prem Kumar Sehgal and Gurbaksh Singh Dhillon are remembered as:

The correct answer is Officers of the Indian National Army.

Explanation:

Colonel Shah Nawaz Khan, Colonel Prem Kumar Sehgal, and Colonel Gurbaksh Singh Dhillon were prominent officers of the Indian National Army (INA), also known as the Azad Hind Fauj, which was led by Netaji Subhash Chandra Bose during World War II.

After the end of the war, these three officers were captured by the British forces and put on trial at the Red Fort in Delhi in 1945–1946, famous as the Red Fort Trials or INA Trials. They were charged with treason and waging war against the British Empire.

The trial sparked widespread national outrage and solidarity across India. The Indian National Congress set up an INA Defence Committee comprising legendary lawyers such as Bhulabhai Desai, Tej Bahadur Sapru, Kailash Nath Katju, and Jawaharlal Nehru to defend them. Due to public pressure and unrest within the armed forces, the British government ultimately remitted their sentences of transportation for life.
