Jacob read the following information in an online science article:

tiny nerve endings in the ear are easily damaged. the risk of any permanent damage depends on the volume and the length of exposure. for instance, people using ear buds or earphones usually have the volume above level five, which can be a problem. also, sitting as close as ten feet away from speakers at a concert can hurt your ears. always allow twenty-four hours of rest for your ears after such an exposure to loud volume.

what could jacob claim in a research paper using the supporting evidence in the text?
a. nerve endings in the human ear are tiny and sensitive.
b. heavy and continued exposure to loud sounds can cause permanent hearing loss.
c. family history is important to hearing loss regardless of whether or not a person has had heavy exposure to loud sounds.
d. people who use ear buds are more likely to damage their hearing than people who listen through wireless speakers.
