Five-Year-Old Sophie Is Playing with Blocks

Five-year-old Sophie is playing with blocks.She stacks them one on top of another until her towers eventually tumble, and then she begins stacking them again.Which one of the following best reflects Piaget's view of how Sophie is probably learning in this situation?

A) She is probably still in the sensorimotor stage, so she will remember what she learns about the blocks only while the blocks are still in front of her.
B) She is absorbing information about how the environment behaves (e.g., "objects fall") without consciously thinking about it.
C) She is actively thinking about and interpreting the results of her actions.
D) Since she builds one tower after another, she is obviously reinforced by watching her towers tumble down.
