What is a concise description of a trade-off?

• A. The choice between two alternatives when resources are scarce
• B. The difference between revenue and cost
• C. The assessment of demand elasticity
• D. The cost of raw materials per unit

Answer: (A)

A trade-off arises whenever resources are limited, forcing a choice between two or more alternatives. The concise description is the choice between two alternatives when resources are scarce. In business, you must decide how to allocate finite time, money, or materials, so selecting one option means giving up another. This is what “trade-off” captures: you balance competing options because you can’t have everything at once. The other ideas describe different concepts—profit (revenue minus cost), how demand responds to price (elasticity), or the cost of inputs per unit—not the general idea of choosing between alternatives under scarcity.
