Notion refers to which of the following?

• A. A mental image
• B. An idea, belief or opinion about something
• C. A physical object
• D. A guess

Answer: (B)

Notion is used to mean an idea, belief, or opinion about something. It conveys your general understanding or viewpoint rather than a specific mental picture or a guess. A mental image is a visual representation in your mind, which is related but not the same as a notion. A guess is a tentative answer without solid basis, whereas a notion implies a more formed belief or principle you hold about a topic. For example, “My notion of fairness is that everyone should have the same starting point” uses notion to express a principles-based belief about fairness.
