Verified step by step guidance

1. Understand the concept of scarcity in microeconomics: Scarcity arises because resources available to produce goods and services are limited, while human wants and needs are unlimited.
2. Recognize that scarcity is a fundamental economic problem that forces individuals and societies to make choices about how to allocate resources efficiently.
3. Evaluate the given options by comparing them to the definition of scarcity: Prices increasing, rational choices, and renewable resources do not directly explain scarcity.
4. Identify that the correct explanation for scarcity is that resources are limited (finite) whereas human wants are unlimited, creating a gap that necessitates decision-making.
5. Conclude that scarcity is the reason why economics studies how to allocate limited resources to satisfy unlimited wants, which is the basis for all economic activity.
