[单项选择]Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu (流感)may make a difference in how long the misery lasts.
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That’s because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses--flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine(疫苗) , which is, for most people, the best way to fight the flu, according to the ALA.

A. one doesn’t need to take any medicine if he has a cold or the flu
B. aspirin should not be included in over-the-counter medicines for the flu
C. delayed treatment of the flu will harm the liver and central nervous system
D. over-the-counter drugs can be taken to ease the misery caused by a cold or the flu
