The correct answer is B) with Oceans on both sides, most countries have access to many seaports and trade routes.
The option that describes how the physical feature of countries in North America influence trade in these countries is that with Oceans on both sides, most countries have access to many seaports and trade routes.
This is clearly the case of countries such as Mexico, the United States, and Canada. These countries are blessed for their geographical location, having tho oceans, the Atlantic, and the Pacific Ocean on each side. This allows them to have access to many seaports and trade routes. This advantage plays a big role in Commerce agreement such as in the case of NAFTA, the North American Free Trade Agreement, that recently was changed to USMCA, United States, Mexico, and Canada Agreement. These ports can connect ships to all the world.
