Which of the following is an example of rational decision-making?

The correct choice demonstrates rational decision-making because it involves a systematic process of evaluating multiple options based on their expected outcomes. Rational decision-making relies on a thorough analysis of available information, weighing the potential benefits and costs of each option before arriving at a conclusion. This method ensures that choices are made to maximize positive results or minimize negative consequences, aligning with the principles of classical economic theory, which assumes that individuals act in their best interest based on logical analysis.

Choosing between options based on past experiences can be informative, but it doesn't necessarily involve an objective evaluation of current choices or their outcomes. Picking the first option without consideration lacks a rational approach, as it disregards the analysis of potential alternatives. Deciding based on popular opinion also does not reflect rational decision-making, as it relies on external influence rather than a personal assessment of the options at hand. Hence, the selected answer best exemplifies the idea of making rational, informed decisions in economics.
