Step-by-step explanation:
option B is correct
When creating a nutritional plan for consumption during endurance activities, the most important focus should be on hydration levels. While all the options listed in the question are important, maintaining proper hydration is crucial for sustaining performance and preventing dehydration.
During endurance activities, the body loses water through sweating, and dehydration can negatively impact performance. It is recommended to drink water or sports drinks before, during, and after exercise to replace lost fluids and maintain hydration levels.
While carbohydrates, protein, and electrolyte balance are important for overall nutrition, prioritizing hydration is key in supporting endurance activities and maximizing performance.
