Coch Suffered from Painful Arthritis

Coch suffered from painful arthritis. Dr. Brooke prescribed an FDA-approved drug made by Sterling that was known to help treat this disease. Sterling knew the drug could cause vision problems and warned doctors about this. Brooke warned Coch of the possible side effects of the drug. After three year's use, Coch began to suffer blurred vision, so Brooke stopped prescribing the medication. Later Coch went blind, probably from the drug. Coch sued the doctor and the drug company. in this case a court would probably:

A) hold Dr. Brooke and Sterling drug and FDA liable
B) hold Dr. Brooke and Sterling drug liable
C) hold Dr. Brooke liable
D) hold Sterling drug company liable
E) find no liability due to assumption of risk for unavoidably dangerous product
