Final answer:
Whether Wayne's parents can claim him as a dependent depends on his student status.
Step-by-step explanation:
Based on the given information, Wayne earns $4,200 during 2017 and is not disabled. To determine whether Wayne's parents can claim him as a dependent, we need to consider if he is a full-time student. If Wayne is a full-time student, his parents can claim him as a dependent; if not, they cannot claim him. The question does not provide information about Wayne's student status, so we cannot definitively determine whether Wayne's parents can claim him as a dependent.
