I believe the answer is Information.
In the past, information could be easily controlled since only radio and television media have the ability to provide it to the mass.
In recent years, the development of internet and social media have make the spread of information could no longer be controlled by the government.
The correct answer is b. Store. A store is not residential, as it serves storage and exchange of goods (for Money). All the other options ARE residential : people live in them.
A command economy is an economy in which production, investment, prices, and incomes are determined centrally by a government.
Hope This Helps!!!
