I have been asked this question in semester exam.

This is a very interesting question from Photochemical Reactions topic in section Photochemistry of Engineering Chemistry I

Answer 1

Correct choice is (a) to prevent the drug from photodegradation

Best explanation: Medicine bottles are often made with darkened glass to prevent the drugs from photodegradation. Generally, brown color is used because of its ability to prevent UV light from degrading the potentially photosensitive contents through photochemical reactions.
