Final answer:
The answer to the question is option C and D. Consumers have limited amounts of money, and goods are scarce relative to the demand for them.
Step-by-step explanation:
Scarcity is a concept at the center of economics. The condition of scarcity forces decision making because individuals will always desire more than what they can have. This means that consumers have limited amounts of money, which is option C in the question. Goods are scarce relative to the demand for them, which is option D. These two options drive home the reality of scarcity to each consumer because they highlight the limited availability of goods and the need to make choices due to limited resources.
