Option A: Red Shirt
Detailed Solution:
The correct answer is “Red Shirt”.
Khan Abdul Gaffar Khan, also known as Bacha Khan or the Frontier Gandhi, started the movement known as the Red Shirt movement against the British colonial rule in India.
The Red Shirt movement was launched in the North-West Frontier Province of British India in the 1920s and 1930s. It was a nonviolent resistance movement inspired by the principles of nonviolence and civil disobedience advocated by Mahatma Gandhi.
The Red Shirts, also called the Khudai Khidmatgar (Servants of God), wore distinctive red shirts as a symbol of their movement. They organized protests, strikes, and acts of civil disobedience against the British authorities.
