What is a major economic activity in Mexico?

The correct answer is that all of the options presented—agriculture, mining, and tourism—constitute significant economic activities in Mexico. Each of these sectors plays a vital role in the country's economy.

Agriculture is important due to Mexico's diverse climate and geography, allowing it to produce a variety of crops, including corn, avocados, and tropical fruits. This sector not only feeds the population but also contributes to exports.

Mining is another key economic activity, with Mexico being rich in mineral resources such as silver, gold, and copper. The mining industry has a long history in the country and continues to be a major contributor to the economic landscape.

Tourism is also a critical component of Mexico's economy. The country is famous for its rich cultural heritage, historical sites, and beautiful beaches, attracting millions of visitors each year. This influx of tourism revenue supports jobs and stimulates local economies throughout the country.

Given that all three activities are integral to Mexico's economic framework, the option that includes all of them is the most accurate choice.
