The correct option is A Partition of Bengal
The Swadeshi Movement started with the partition of Bengal by the Viceroy of India, Lord Curzon, in 1905 and continued up to 1911. It was the most successful of the pre-Gandhian movement.
The term 'Swadeshi' implies the use of products and services of one's own country. The Swadeshi Movement advocated the boycott of foreign goods and British institutions. It also advocated mass mobilizations which saw many people come together to raise awareness and demand swaraj.
