Explanation:

When a country have  a comparative advantage, its cost of producing a specific product will be cheaper compared to another country.

Let's say that there are two countries.

Country A and Country B. Country A able to produce rice in a really low cost  (opportunity cost for producing other products beside rice is higher) . Country B able to produce meat in a really low cost. (opportunity cost to product other products beside meat is higher)
