2. "Smoking trends of adolescents": This option pertains to the study of adolescent behavior, specifically their smoking habits. Developmental psychologists often explore various aspects of adolescent development, including risky behaviors and substance use. Therefore, this option falls under the purview of developmental psychology.

5. "How personality develops across the lifespan": This option considers the study of personality development over the course of an individual's life. This encompasses changes in personality traits and characteristics from childhood to adulthood, which is a central area of exploration for developmental psychologists.
