Step-by-step explanation:
The correct statement is D. Audimeters only record what is being watched, while people meters can also record who is watching.
Audimeters are devices that track what television programs are being watched. They record data such as the channel, time, and length of viewing. People meters, on the other hand, not only record what is being watched but also who is watching by utilizing demographic information. This allows advertisers and television companies to gather more detailed information about their viewership.
