Explanation:

Here’s the thing, let’s break down the options:

- Option 1: 1911

Gandhi was still working in South Africa during this year, leading protests and movements there. He hadn’t arrived in India yet.

- Option 2: 1909

This year is important because Gandhi visited England (he wrote “Hind Swaraj” then) on his way from South Africa, not India. He didn’t settle in India at this time.

- Option 3: 1913

Gandhi was deeply involved in the South African civil rights struggle, especially around the issues faced by Indian workers. He hadn’t returned to India yet.

- Option 4: 1915

This is the correct answer. Gandhi finally returned to India from South Africa in 1915 and soon began his leadership in the Indian independence movement.

So, . 1915 is absolutely correct. Gandhi landed in Bombay (now Mumbai) in January 1915, marking the start of a new chapter in India’s freedom movement.
