The correct answer is option 4, India. India has the highest percentage of land under cultivation compared to the other options listed. This means that a larger portion of India`s land is used for growing crops or raising livestock.
China, option 1, is also a large agricultural country, but India has a higher percentage of land dedicated to cultivation.
The U.S.A., option 2, has a significant agricultural industry, but it does not have as much land under cultivation as India.
Canada, option 3, is known for its vast agricultural lands, but again, India has a higher percentage of land under cultivation.
It is important to note that this answer is based on statistics and can vary depending on the time period and specific data used.
