Final answer:
No, a minor cannot do repairs in a business where Class A minors are prohibited, regardless of parental consent, due to legal restrictions on the employment of minors.
Step-by-step explanation:
The question, concerning whether or not a minor can do repairs in a business where Class A minors are prohibited, falls under the area of Law. The Law typically states that minors require parental consent for certain activities because they are not legally competent to provide consent for themselves. However, when it comes to working in environments that are prohibited for Class A minors, the law is clear that they cannot engage in any kind of work, including repairs, regardless of parental consent. Therefore, the correct answer to the question is b) No, regardless of circumstances.
