The correct answer is B. Closed Economy
Step-by-step explanation:
A closed economy, also called closed-household is an economic system in which products and goods are both produced and consumed in the same country or by the same households, this implies exports and imports do not take place and thus, trade with other countries is not possible. Additionally, a closed economy is considered as a self-sufficient economy as consumers get everything they need from companies in their country and do not require international trade to have a stable economy. However as trade in terms of import and export are not possible, buying goods or services from other countries is difficult.
