Which one of the following is NOT a significant property of attitude?

Quantity

The correct answer is Option (4) → Quantity

Four significant features of attitudes are : Valence (positivity or negativity), Extremeness, Simplicity or Complexity (multiplexity), and Centrality.

Valence refers to the direction of an attitude, meaning whether it is positive or negative towards an object or issue. Extremeness describes the intensity of that attitude, indicating how strongly positive or negative it is. Centrality relates to the importance of the attitude, or how deeply it is integrated into a person's core values and self-concept.  Simplicity or Complexity refers to how many attitudes there are within a broader attitude.
