Step-by-step explanation:
The correct answer is B. It is the percentage of TV households in an area that are tuned to a specific program during a specific time period.
Program rating refers to the percentage of TV households that are watching a particular program at a given time. It is a way of measuring the popularity and viewership of a program. For example, if a program has a 10% rating, it means that 10% of the TV households in a specific area are tuned in to that program.
This measurement is important for advertisers and networks as it helps them understand the reach and impact of a program, which in turn influences advertising rates and programming decisions.
