According to Jean Piaget's theory of cognitive development, at which stage do most children particularly face difficulty in understanding the point of view of another person?

Correct option is B

(b) Pre-operational
In Piaget's theory, the pre-operational stage, typically from ages 2 to 7, is where children struggle with understanding the perspective of others. This stage is characterized by egocentrism, where children find it difficult to see things from viewpoints other than their own. They are not yet able to perform operations (mental processes that allow logical thought).
