Show Worked Solution
  • B is correct: Sports drinks replace both fluids and critical electrolytes like sodium needed for neuromuscular function.

Other Options:

  • A is incorrect: Rapid water consumption without electrolytes can cause hyponatremia after prolonged exercise.
  • C is incorrect: Thirst occurs after significant dehydration – immediate rehydration is necessary.
  • D is incorrect: High sugar content in fruit juice slows absorption and lacks optimal electrolyte balance.
