The correct answer is b) exports.
Exports refer to the goods and services that a country sells to foreign markets and sends out of its borders. These transactions are vital for a country’s economy as they generate revenue, create jobs, and contribute to the overall economic growth. In contrast, imports are goods and services brought into the country from abroad. Understanding the distinction between exports and imports is crucial in the field of economics, as it helps to assess a nation’s trade balance and economic health.
