Who was the first Viceroy of India?

The correct answer is Lord Canning.

Explanation:

Lord Canning served as the Governor-General of India from 1856 to 1858. Following the Indian Rebellion of 1857, the British Parliament passed the Government of India Act 1858, which abolished the rule of the British East India Company and transferred the administration of India directly to the British Crown.

Under this Act, the title of Governor-General was combined with that of Viceroy, making Lord Canning the very first Viceroy of India. He served in this role as Viceroy from 1858 until 1862.
