Reasoning, curiosity and observation are developed at the age of ____________.

Correct option is A

The development of reasoning, curiosity, and observation is most prominent during the age of 7 to 11 years, which corresponds to the Concrete Operational Stage as defined by Jean Piaget in his theory of cognitive development. At this stage, children develop logical thinking, improve their ability to reason, and become more curious about their surroundings. They also begin to observe and analyze their environment systematically. This stage marks a shift from egocentric thinking to understanding multiple perspectives.

Information Booster:

1. Concrete Operational Stage (7–11 years): Logical reasoning skills, classification, and conservation concepts are developed.
2. Curiosity: Children actively explore and question their surroundings, seeking logical explanations.
3. Observation: They begin to observe relationships and patterns in their environment.
4. Problem-Solving: This age introduces systematic problem-solving abilities.
5. Critical Thinking: The ability to think critically about their experiences starts to emerge.

Additional Knowledge:

(B) 3 to 5 years:

• This age falls under Piaget's Preoperational Stage (2–7 years), where symbolic thinking, imagination, and language development are key features.
• However, reasoning is not yet logical, and thinking is egocentric (focused on their own perspective).

(C) 5 to 7 years:

• During this transitional period, children begin to move from the Preoperational Stage to the Concrete Operational Stage.
• Basic reasoning and curiosity develop, but systematic observation and logical reasoning are not fully mature.

(D) 11 to 13 years:

• This period marks the Formal Operational Stage, where abstract thinking and hypothetical reasoning are developed.
• While curiosity and observation continue, they are more focused on abstract ideas rather than concrete situations.
