Consider the following:<br/>1. Assessment of land revenue on the basis of nature of the soil and the quality of crops.<br/>2. Use of mobile cannons in warfare.<br/>3. Cultivation of tobacco and red chillies.<br/><br/>Which of the above was/were introduced into India by the English?

1. Assessment of land revenue on the basis of soil and crop quality — This is associated with Sher Shah Suri/Akbar-Todar Mal revenue practices, not an English introduction. Verdict: Incorrect.

2. Use of mobile cannons in warfare — Field/mobile artillery was introduced earlier by Babur and other Central Asian powers, not by the English. Verdict: Incorrect.

3. Cultivation of tobacco and red chillies — These were New World crops brought by the Portuguese into India, not by the English. Verdict: Incorrect.

Since none of the above was introduced by the English, the correct answer is (d) None.
