Correct option is B
The "Economic Drain" theory was popularized by Dadabhai Naoroji, often referred to as the "Grand Old Man of India." He was one of the earliest Indian leaders to systematically highlight the negative impact of British colonial rule on India’s economy.
Dadabhai Naoroji's Contribution:
In his book "Poverty and Un-British Rule in India" (1901), Naoroji laid out the Economic Drain Theory, explaining how the British exploited India's resources and transferred wealth back to Britain, leading to poverty and economic stagnation in India.
He argued that a significant portion of India's wealth was being drained to Britain through various means, such as:
- High taxes.
- Unfair trade practices.
- Payments to British officials and military personnel in India.
- Profits from Indian industries sent to Britain.
