National Public Radio (NPR) often holds fund drives to raise money for their radio stations. They frequently offer prizes for people who donate a certain amount of money. For example, they might offer a CD for those who donate at least $50 to the station. It is not clear whether this actually increases donations. What can we say about this situation

Hello. You forgot to enter the answer options. The options are:

"The money functions as a reinforcer for getting a CD.  The CD's function as a reinforcer for donating money.  The money functions as a reward for getting a CD.  The CD's function as a reward for donating money."

The CD's function as a reward for donating money.

Explanation:

As seen in the question above, Rádio Pública Nacional participates in a campaign that seeks to raise funds to maintain its radio stations.

As we know today, radio stations do not have as many listeners as before, this is because of our busy way of life and the technologies that have made radio something absolute in some ways. For this reason, the National Public Radio looked for a way to reward those people who help it, for this reason, it offers a CD to each person who makes a donation, as a reward for their generosity.

i am pretty sure it is d.
