Preoperational intelligence:

A) allows children to think in symbols.
B) includes logical reasoning.
C) is characterized by reversibility of thought.
D) relies primarily on children's motor skills and senses.

According to Piaget's theory of cognitive development, preoperational intelligence is characterized by the development of symbolic thinking, which allows children to use words, images, and gestures to represent objects and concepts that are not present. This type of thinking enables them to engage in imaginative play and language use. Logical reasoning and reversibility of thought develop later, in the concrete operational stage. Preoperational intelligence also relies on children's motor skills and senses, but this is not the main characteristic of this stage.
