Your question asks which student is correct.
The reason why "neither of the students are correct" is correct because the students said things that actually do not belong in the commercial sector.
The commercial sector includes places like restaurants, healthcare facilities, educational institutions, and hotels.
Lets list out what the students said:
Automobiles
Churches
Construction
The automobile businesses would be part of the industrial sector, due to the fact that they're taking raw material and producing products (vehicles) that people would buy. Automobile businesses build their vehicles in industrial factories. This is what makes them under the industrial sector.
A church would be under it's own organization. Churches could be a non-profit organization. Churches pretty much could be under the "service industry", but it wouldn't be under a energy sector.
Construction would be under the industrial sector. The reason for that is because they're the ones that build things like buildings, houses, etc. Construction wouldn't be under the commercial sector, due to the fact that it's not commercial.
Answer: Both are incorrect
Explanation: the commercial sector does not include automobiles or construction
