Anthony is able to think about "what might be," not only about "what is." According to Piaget, Anthony is in which stage of cognitive development?

Anthony is in the formal operational stage.

Explanation:

According to Jean Piaget's theory of cognitive development, Anthony is in the fourth and final stage. This is the most advanced stage of cognition, beginning at age 12 and lasting throughout adulthood. From this point on, children are able to think about abstract concepts and theories. They are also able to use logic to solve problems. Notice how Anthony can think of what is and what might be. He is using abstract thinking, theorizing about possibilities.
