A.I. Explanation:

Option 1: "The history of art through the ages"

Option 2: "The impact of art on urban development"

Explanation: This option is incorrect as the text does not mention urban development at all. The main focus is on mental health and self-expression through art, which is unrelated to urban issues.

Option 3: "The relationship between art and mental health"

Explanation: This option is correct because the text explicitly states that the exhibition explores the intricate relationship between art and mental health. This is the central theme of the exhibition, as it highlights self-expression, healing, and the psychological impact of creativity.
