Answer:
B
Explanation:
Ratings does not have affect on the validity of the source, it only shows the exposure said show/source received the day it was aired. It doesn't mean anything in terms of reliability.
Meanwhile exaggeration, leaving out information, and reformatting events for entertainment purposes all have great impacts on the reliability of a source.
The other options are very important questions while reviewing any source but in this case B is the correct option.
