The most appropriate group of qualities in reference of adolescent boys and girls is:

Question

Accepted Answer

The correct option is 2:
Adolescence, which typically spans from 12 to 18 years, is the period characterized by the transition to Jean Piaget’s Formal Operational Stage of cognitive development. This stage fundamentally changes how individuals think, enabling them to engage in **Abstract thinking**, which involves considering possibilities beyond concrete reality, such as justice, morality, and future hypotheticals. Simultaneously, there is a marked improvement in **Reasoning** abilities, allowing adolescents to use deductive logic, test hypotheses systematically, and evaluate arguments critically. The combination of these higher-order cognitive skills leads to the development of **Decision-making** capabilities, as they are increasingly able to weigh complex consequences and make informed choices about their academic, social, and personal futures. This group of qualities—Abstract thinking, Reasoning, and Decision-making—represents the most fundamental and pervasive cognitive advancements defining the adolescent period.

The incorrect option is 1:
While adolescents do develop a sense of **Self-respect** and often strive for high **Ideal**s, the term **Good adjustment** is not a defining cognitive characteristic of this stage, as adolescence is often marked by periods of emotional turmoil and stress, famously termed by G. Stanley Hall as a period of "storm and stress."

The incorrect option is 3:
**Observation** and **Habit of repetition** are key learning mechanisms more characteristic of infancy and childhood (sensorimotor and preoperational stages), rather than being primary defining characteristics of adolescence. While a **Feeling of revolt** may be present in some adolescents, it is a socio-emotional trait, not a universal cognitive quality like abstract thinking and reasoning.

The incorrect option is 4:
The development of **Philosophy** (or philosophical thought) is an advanced outcome of abstract thinking, but the group omits the core developmental mechanisms of reasoning and abstract thinking itself. **Good adjustment** is not a primary characteristic, and a strong **Feeling of social service** is an admirable but highly variable moral characteristic, not a universal cognitive marker of the age group.
