When an individual chooses his or her ideal career, it is most likely a reflection of one's answer
a. values
b. hobbies
c. education
d. skills

I would say that it's not education or skills, as those can be acquired later. So, for example when you choose your major in a college, you do it based on what you want to learn, not what You already know.

The best answer is: Hobbies, which is similar to interest.
