Correct option is B
General IQ scores are a measure of cognitive abilities and are often divided into two categories: fluid intelligence and crystallized intelligence. Research suggests that fluid intelligence, which involves problem-solving, reasoning, and processing speed, tends to peak in early adulthood, around 25 years of age. On the other hand, crystallized intelligence, which includes accumulated knowledge and vocabulary, continues to improve well into middle age.
Studies using large datasets, such as those conducted by psychologists like Joshua Hartshorne and Laura Germine (2015), indicate that certain cognitive abilities, particularly processing speed and problem-solving, tend to peak around the mid-20s and gradually decline afterward. This is because the brain's neural efficiency and synaptic plasticity are at their highest during this period.
