Which of the following is a correct association of sensory problems?

A) color blindness-lack of red or green cones
B) deafness-infection with certain viruses such as the rubella virus
C) otosclerosis-new bones overgrow the stirrup, requiring surgery
D) cataracts-lens becomes opaque with aging and sun exposure
E) All of the answer choices are correct associations.

All of the answer choices are correct associations. Color blindness is caused by the lack of red or green cones in the retina, deafness can result from infections with viruses such as rubella, otosclerosis is the abnormal overgrowth of bone in the middle ear that can cause hearing loss and requires surgery to correct, and cataracts are caused by changes in the lens that make it opaque with aging and exposure to UV light.
