According to Piaget, many 16 year-olds have reached the cognitive stage called formal operational thought.

According to Piaget's theory of cognitive development, which describes how individuals develop their thinking abilities, the cognitive stage reached by many 16-year-olds is the formal operational stage.

To arrive at this answer, we need to understand Piaget's stages of cognitive development and determine which stage aligns with the cognitive abilities typically seen in 16-year-olds.

Piaget proposed that individuals progress through four stages of cognitive development: sensorimotor, preoperational, concrete operational, and formal operational.

The sensorimotor stage (from birth to approximately 2 years old) is characterized by a focus on sensory experiences and motor actions. The preoperational stage (from around 2 to 7 years old) is marked by the development of symbolic representation and egocentrism.

The concrete operational stage (from about 7 to 11 years old) sees the emergence of logical reasoning abilities, but thinking remains limited to concrete, tangible situations.

Last comes the formal operational stage, which typically starts around adolescence (around 11 or 12 years old) and extends into adulthood. This stage is characterized by the ability to think logically and systematically about abstract concepts and hypothetical situations.

Given that 16-year-olds are generally within the age range associated with formal operational thought, the correct answer to the question is b. Formal operational thought.
