The book 'Poverty and Un-British Rule' was written by Dadabhai Naoroji to explain a theory as to how British drained India's wealth. The book was written and published in the year 1901. Dadabhai Naoroji? describes 6 factors that were causing the draining of wealth. The government ruling in India was not its own, it was foreign. There was no immigration to India, which would have been an influx of wealth to the country. Britain was not paying for the East India Company's operation or the Indian army of that time. India was the one paying. Bearing the burden of empire building in and out the borders of the country was borne by India, and not Britain. Foreign people were given priority for jobs over Indians who were equally qualified to hold the position. Wealth left India when the earners spend money outside of India rather than within the country. Hence, the correct answer is Dadabhai Naoroji
