Answer: b. The foreign sector influences how imports and exports move between firms and households.
Explanation:
The foreign sector provides goods and services to households from other countries but this is usually done via a firm in the country.
Goods therefore come in via imports from outside the country from the foreign sector exporting goods and services to local firms. These firms would then pass it on to households completing a circle of the foreign sector influencing how exports move between firms and households.
