Answer:
The best evaluation for Kenton's research is C) Poor; he has only researched the monetary costs of the career.
Step-by-step explanation:
Besides monetary costs to him (which was not all that comprehensive as it didn't include training tools, books, etc) there are also non-monetary costs such as time, hard work, and all the other things he must forego while he is focused on becoming a make-up artist.
The career also comes with its perks and advantages. Kenton's work would have been comprehensive if he researched the benefits as well as the risks, and regulatory requirements where there are any.
Cheers
