Which symptom is commonly associated with inhalation of smoke containing carbon monoxide?

Explanation:
When smoke is inhaled, carbon monoxide binds strongly to hemoglobin to form carboxyhemoglobin, which prevents oxygen from getting to tissues. The brain and other vital organs then experience hypoxia, so the most common early symptoms are headache and dizziness as oxygen delivery is compromised. Nausea can occur but is less specific, while fever and rash aren’t typical features of carbon monoxide poisoning. So, headache and dizziness is the symptom most commonly associated with inhaling smoke containing carbon monoxide.
