See answer and applicable Code reference
The correct answer is: b) False
Article 705 covers installation of one or more electric power production sources operating in parallel with a primary source(s) of electricity. As noted in the second sentence of the definition for "hybrid system" (705.2), "These power sources could include photovoltaic, wind, micro-hydro generators, engine-driven generators, and others, but do not include electric power production and distribution network systems."
