A recent study has provided evidence that two types of equine (horse) herpes viruses have an unusually broad host range. This fact supports which of the following statements?
a. The lytic cylce occurs in horses while the lysogenic cycle occurs only in other species.
b. The virus is transmitted from one host to another by mosquitoes.
c. In a population of horses, many of the individuals will become infected
d. Horses, rhinoceroses, and polar bear can become infected
e. In an individual horse, many different type of cells will be infected
According to the answer key, the answer is D. My question is why isn't E also a correct answer? I thought host range means "the range of cells that can act as a host to a virus".
