In the circular flow model for goods and services:
- (i) is correct: households sell their factors of production (like labor, land, and capital) to the factor market where they are purchased by firms.
- (ii) is missing in the given options, but it would state that households consume goods and services offered on the goods market.
- (iii) is correct: firms combine factors of production and produce goods and services.
- (iv) is incorrect as goods and services are offered for sale on the goods market, not the factor market.
Therefore, the correct choices are:
A. Only (i).
B. Only (i) and (iii).
These choices accurately represent the flow of goods, services, and factors of production in the circular flow model.
