How is personality defined?

Personality is best defined as a totality of attitudes, interests, and emotional responses. This encapsulation reflects the complex interplay of various internal factors that shape how an individual thinks, behaves, and interacts with others. It encompasses a person's unique patterns of thoughts, feelings, and behaviors that are consistent over time and across different situations, thus providing a more holistic understanding of an individual's character.

The other options do not accurately capture the essence of personality. For instance, a person's clothing style or social circle may reflect certain aspects of their personality but do not define it comprehensively. Similarly, IQ is a measure of cognitive abilities, which is distinct from the broader concept of personality that includes emotional and social dimensions. Therefore, the definition recognizing personality as a totality of attitudes and emotional responses is the most accurate and complete representation of what personality entails.
