d. Optometrist
e. Ophthalmologist

Option (B). Psychoacoustician

Explanation: it is the branch of science studying the psychological responses associated with sound (including noise, speech, and music). The main objective of psychoacoustics is to understand how people perceive and experience sound. This can be at a low level; for example, we might want to understand how accurately you can locate a sound source, or we might want to measure the smallest change in sound level you can detect.

However, If you are building a pair of high-tech headphones and want to have the best sound possible for listening to music, Psychoacoustician is the kind of scientist that should be hired to help develop the product. Ultimately, all sound that we perceive is psychoacoustic. As soon as sound passes through the ears, it stops being a physical phenomena and becomes a matter of perception.
