Which of the following is a symptom of food poisoning?

• A. Headaches
• B. Sore throat
• C. Coughing
• D. Rash

Answer: (A)

Headache is a possible symptom of food poisoning because illness from contaminated food can cause dehydration and the body's reaction to toxins, which can lead to a head pain. Food poisoning usually shows up with nausea, vomiting, stomach cramps, diarrhea, and sometimes fever or dehydration; headaches can occur as dehydration develops or as a general response to toxins. The other options—sore throat, coughing, and rash—are not typical signs of food poisoning and are more commonly linked to respiratory infections or allergic reactions.
