Final Answer:
When a single-car garage is attached to a house, the NEC requires that the garage have at least one receptacle on every exterior wall. Option D is the answer.
Step-by-step explanation:
The National Electrical Code (NEC) outlines safety standards for electrical installations. In the context of a single-car garage attached to a house, the NEC specifies that the garage should have at least one receptacle on every exterior wall. This requirement ensures that electrical outlets are conveniently distributed, allowing for the use of power tools, lighting, or other electrical devices in various locations within the garage.
Options (a), (b), and (c) do not accurately reflect the NEC requirement for a single-car garage attached to a house. The correct requirement is to have at least one receptacle on every exterior wall.
Option D is the answer.
