1. what are opportunity costs?

a the value or cost of choosing one thing over another
b the trade - off you make when you choose to spend money for something
c the value you give up in a buying choice
d all of the above

1. consumers choices are limited by:

a scarcity of goods
b scarcity of money
c both a and b
d none of the above

Explanation:

1. When consumers buy a product, they imply it's good (so producers should keep making it), resources should be used for it (as there's demand), and the price is reasonable (they are willing to pay). So all options A, B, C are correct, making D the answer.
2. By definition, a consumer is an individual who buys goods and services for their own use. Businesses buying to make products to sell are more like intermediate users in a production - consumption chain, and government agencies are a specific type of buyer but the core definition is about individual end - users for personal use.
3. Opportunity cost is defined as the value or cost of choosing one thing over another (A), it involves the trade - off when spending money (B) (e.g., choosing to buy a book means not buying a coffee, and the value of the coffee is the opportunity cost), and it is the value given up in a buying choice (C). So D (all of the above) is correct.
4. Consumers' choices are limited by the scarcity of goods (if a good is scarce, they may not be able to buy as much as they want) and scarcity of money (their budget constraints). So C (both A and B) is correct.
