By which one of the following Acts was the Governor General of Bengal designated as the Governor General of India?
Explanation
The Charter Act of 1833 centralized the administration of British India by redesignating the Governor-General of Bengal as the Governor-General of India, vesting in him all civil and military powers. While the Regulating Act of 1773 is a common point of confusion, it only elevated the Governor of Bengal to the status of 'Governor-General of Bengal' and made other presidencies subordinate to him. This question tests the core concept of the constitutional evolution and administrative centralization of British rule in India.
