Final answer:
States that require physical education courses show improved academic performance.
Step-by-step explanation:
The correct answer to the question is B. States that require physical education courses show improved academic performance.
Research has shown that physical education can positively impact academic performance by improving cognitive function, attention, and memory. Regular physical activity can also reduce stress and improve mood, which can have a positive effect on students' ability to focus and learn.
For example, a study conducted by the Centers for Disease Control and Prevention found that students who participated in daily physical education classes had higher test scores in reading, math, and science compared to students who had fewer physical education classes or none at all.
