Robyn is working on her presentation for speech class. She is giving an informative speech about the rising cost of apartments. Robyn needs one more source and decides to look online to find more information. She came across a site that is run by an individual who owns and rents out housing units across the region. It contains all kinds of information about the history and statistics of apartment rentals in recent years.

Why might Robyn decide not to use this source?
A.
The person who runs the site probably obtained most of his or her information from others.
B.
A person who rents out housing units may write in favor of one side of the issue.
C.
A person who owns and rents out housing units probably doesn't know much about the history of rental costs.
D.
The person who runs a site about rental costs is probably for lowering those costs.
