\(B\)

Show Worked Solution
  • B is correct: Severe stomach cramps indicate significant digestive distress, while confusion can signal low blood glucose, showing the endocrine system can no longer maintain energy supply to the brain.

Other Options:

  • A is incorrect: Sweating and mild nausea are common during endurance events and can be managed by slowing down and taking fluids.
  • C is incorrect: Muscle fatigue and thirst are expected at this stage of a marathon.
  • D is incorrect: Light-headedness and hunger are early signs of falling blood glucose that can be managed with race nutrition before first aid is needed.
