Which of the following costs is often important in decision making, but is omitted from conventional accounting records? A. Fixed cost. B. Opportunity cost. C. Sunk cost. D. Indirect cost.

The correct option is B - Opportunity Cost

Explanation:

Generally, an opportunity cost is the benefit that you gave up when you pass on that option in favor of another option. For instance, by choosing to purchase furniture instead of taking a vacation comes at the cost of not experiencing the relaxation and fun associated with a vacation. All options have opportunity costs (getting married instead of staying single, investing in school instead of retirement, etc).

Everyone should know that opportunity cost is a very important concept that doesn't just have its application in economics; you can apply it to all aspects of your daily life. Whether you're cooking, eating, playing soccer, going to the movies, or hitting the gym, so long as you're breathing, evaluating the choices you're presented with is an inevitability, whether conscious of it or not.
