The concept of choice in Economics refers to

Step 1: Analyze the question The question asks what "choice" means in Economics. It is linked to scarcity: resources are limited and wants are unlimited, so we cannot satisfy every want.

Step 2: Explain the concept Because of scarcity, people must choose which wants to satisfy first. They do this by looking at the available alternatives and selecting the most pressing (most important) one. The wants not selected become the opportunity cost. So in Economics, choice is not just picking between two things. It is picking the most urgent or important want from a range of alternatives, based on a scale of preference.

Step 3: Evaluate the options

• A. A decision between one thing and another: This is a general, everyday meaning. It only covers two items and doesn't say how the decision is made.
• B. Ranking of wants in ascending order: Ranking is the scale of preference, not the choice itself. Also, wants are ranked in descending order of importance, so "ascending" is wrong.
• C. Selection of most pressing wants out of a range of alternatives: This matches the economic meaning. Choice is the act of selecting the most urgent wants from many alternatives.
• D. Ranking of wants on a table of preference: This describes a scale of preference, which is a tool used in making choices rather than the choice.
• E. Separating defective commodities from non-defective ones: This is quality control, not choice.

Step 4: Answer Both choosing and selecting involve decisions, but the economic idea is about picking the most pressing wants from several alternatives because resources are scarce.

Tip: Remember the chain Scarcity → Choice → Scale of Preference → Opportunity Cost. Choice is selecting, the scale of preference is ranking, and opportunity cost is what you give up. When an option says "ranking," think scale of preference; when it says "selection of most pressing," think choice.
