The student wants to paraphrase a quotation from Champ and Freeman to… | Verbal SAT Question

While researching a topic, a student has taken the following notes:

Squirrel pelts were used as commodity money in medieval Russia.
In a commodity money economy, specific goods act as a common unit of monetary exchange that can be used to buy and sell other goods.
In a barter economy, goods are traded directly between parties without the use of money.
Economists Bruce Champ and Scott Freeman: bartering requires that “the person with whom you wish to trade must not only have what you want but also want what you have. The inefficiency is apparent; a great deal of time is spent merely finding someone with whom to trade.”

The student wants to paraphrase a quotation from Champ and Freeman to explain the inefficiency of barter economies. Which choice most effectively uses relevant information from the notes to accomplish this goal?

Champ and Freeman: when “individuals might come to accept one particular good in exchange for others even if they do not wish to consume that good...barter economies essentially become monetary economies.”

The precise alignment of desires that barter economies require, Champ and Freeman contend, makes them inefficient.

Champ and Freeman argue that inefficient barter economies can become monetary economies if a good becomes a unit of exchange.

According to Champ and Freeman, the inefficiencies of barter economies become apparent when goods are traded between parties without the use of money.
