Answer: a. both finished products and intermediate goods
Step-by-step explanation:
Both finished goods and intermediate goods can either be imported or exported. If a company that is selling goods at the merchandising level sources the goods from outside, they would be importing a finished good and the company that sent it to them would be exporting same.
Sometimes however, producers would import an intermediate good to help them finish production or to even develop the good further for instance Apple buying screens for phones from Korea. Apple would be importing a intermediate good in this scenario and Korea would be exporting it.
