An individual's unique and enduring patterns of thinking, feeling, and behaving are calledSelect one:a.somatotype.b.phenotype.c.character.d.personality.

Step 1: Break Down the Problem

To determine the correct answer, we need to define each of the provided options and see which one best fits the description of "an individual's unique and enduring patterns of thinking, feeling, and behaving."

Step 2: Relevant Concepts

1. Somatotype: A classification of human physique based on body shape and composition, not related to behavior or personality.
2. Phenotype: The observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences, also not directly about thinking, feeling, and behaving.
3. Character: Refers to the moral qualities and ethical standards of an individual, which can play a role in behavior, but does not encompass all aspects of thinking and feeling.
4. Personality: Refers to the individual differences in characteristic patterns of thinking, feeling, and behaving. It encompasses the unique aspects of an individual's psyche.

Step 3: Analysis and Detail

Among the four options, "personality" most closely aligns with the description provided in the question. Personality is a psychological construct that encompasses a wide range of human behavior and emotional responses, thus making it the most comprehensive and relevant term.

Step 4: Verify and Summarize

Upon analyzing the definitions, it is clear that "personality" is the appropriate answer. The other options refer to physical traits (somatotype, phenotype) or moral/ethical attributes (character) rather than the broader concept of enduring patterns of thought and behavior.

Final Answer

d. personality
