(c) Intrapersonal Intelligence describes the level of self-awareness someone has, starting from realizing weaknesses, strengths, to recognizing their own feelings.
The passage defines self-awareness as identifying your strengths, weaknesses, and knowing yourself — your beliefs, feelings, and inner qualities. This directly matches option (c). Options (a), (b), and (d) describe interpersonal, logical-mathematical, and spatial intelligence respectively — different types of intelligence altogether.
