Concept:Commerce covers all activities that help in the exchange of goods and services.
Explanation:The scope of commerce is not limited to buying and selling alone.
It is divided into two main parts: trade and aids-to-trade.
Trade refers to the actual exchange of goods and services.
Aids-to-trade include transport, banking, insurance, warehousing, advertising, and communication.
Therefore, commerce includes both trade and the services that support trade.
Home trade, foreign trade, wholesale trade, and retail trade are all components under trade, not the full scope of commerce.
This makes the correct choice option B.
Answer:B. trade and aids-to-trade
