Answer:
Correct answer is D, The ads have a short shelf life.
Step-by-step explanation:
Newspapers are the very common and efficient medium of communication. Newspapers are read by almost every person in every house. They contain news from local to national and from national to international levels. If people or companies want to advertise, they can put ads in newspapers. But the disadvantage of putting ad in a newspaper is that, it has a very short shelf life. New newspapers are delivered every day. And the ads posted in a newspaper last for only a day. If you want to publicize your product or service, you need to put ad in newspaper on daily basis.
