option a is the correct
Step-by-step explanation:
A country's level of trade is measured by its exports of goods and services as a share of its gross domestic product (GDP). This indicates how much of its production the country exports.
It is possible for a country to have a high level of trade while also having a near-balance between exports and imports. This means that even though the country exports a significant portion of its production, it is also importing a similar amount.
