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.
