Answer choices:

A. an architect who has only a part-time assistant

B. a small ice cream shop where only one person works at a time

C. a person who works from home for a larger company

D. a manicurist who works from her home or at clients' houses

I would say D. a manicurist who works from her home or at clients' houses.

It's the logical answer because you're working at yours or other people's houses. You don't have a set place where other people you work for will stay.
