Answer: e. Provision or transfer of goods, services or ideas in return for something of value
Step-by-step explanation:
Exchange is the primary way that transactions are done in the market. In order to get a good, service or idea, something of value must be exchanged for it and this thing need not be cash.
Exchange ensures that people get what they want by giving up something they have so therefore in effect, they value the good or service they are getting more than the good that they are giving up. Exchange is therefore value based.
