Answer:
A). Children's behavior is often goal-directed.
Explanation:
Piaget gave his theory of 'child development' where he elaborates how a child experiences different stages of cognitive development in order to form a mental construct/replica of the world he is surrounded by.
'Goal-directed' behavior is illustrated as the 'infancy' stage of cognitive development in which the child(infant) develops learning of their environment and begins to indulge in the deliberate behavior which is 'goal-oriented' in order to get their goal accomplished.
In the given situation, Gabriel's intentional behavior is exemplified by her distress(upset behavior) when her mother 'forbids her' to get her target 'dangly earrings' accomplished. Thus, option A is the correct answer.
