Answer:
c. Exchange creates value by moving goods from parties who value them less to parties who value them more.
Step-by-step explanation:
Exchange is described as the process of changing some goods for some other goods.
Exchange clearly provides you with the goods you value for, and in exchange for those goods you pay the goods you do not value.
This, results in adding value to the goods acquired by you, and adds value to the goods given by you for the person to whom it is exchanges.
As for example when a cloth is purchased by me for $100 then such adds the value to cloth and because it was worth less than $100 for the seller it has added value to the cloth.
