Answer: (B)

Verified step by step guidance

1. Understand the concept of opportunity cost: In microeconomics, opportunity cost refers to the value of the next best alternative that must be given up when making a decision.
2. Recognize that every economic decision involves trade-offs because resources are scarce and choosing one option means forgoing others.
3. Identify that 'no trade-offs' and 'unlimited resources' are incorrect because scarcity implies limited resources and necessary trade-offs.
4. Note that 'a guaranteed benefit' is not always true since decisions can lead to uncertain outcomes.
5. Conclude that the correct answer is 'an opportunity cost' because every decision requires sacrificing something else.
