Correct option is B
Jean Piaget's theory of cognitive development suggests that the concept of symbolism emerges during the Pre-operational stage, which occurs roughly between the ages of 2 and 7. During this stage, children begin to engage in symbolic play and learn to manipulate symbols, but they don't yet understand concrete logic. This stage is marked by egocentrism and the inability to take the perspective of others.

(a) Sensory motor: In the Sensory motor stage (birth to about 2 years), infants learn about the world through sensory experiences and manipulating objects. Symbolism is not a characteristic of this stage.
(c) Concrete operational: Occurring between 7 and 11 years, the Concrete operational stage is when children gain a better understanding of mental operations. They start thinking logically about concrete events but struggle with abstract or hypothetical concepts.
(d) Formal operational: This stage begins at age 12 and continues into adulthood. It involves the development of abstract thinking and the ability to reason about hypothetical problems. It is not the primary stage for the development of symbolism.
