Quizplus · Accepted Answer

The opportunity cost of a unit of electronics in Country B is the amount of food production that is sacrificed for producing one unit of electronics. 
We can calculate the opportunity cost of one unit of electronics in Country B by dividing the amount of food produced by the amount of electronics produced.

Opportunity cost of one unit of electronics in Country B = Food production/Electronics production

From the table, we can see that one worker in Country B can produce either 20 units of food or 10 units of electronics.

So, Opportunity cost of one unit of electronics in Country B = 20/10 = 2 units of food

Therefore, the correct answer is B) 2 units of food.
