Identify the Odd One Out:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Kidney
Option (1) Hypertension — a disease: blood pressure that stays higher than normal.
Option (2) Ulcer — a disease: an open sore, as in the lining of the stomach (peptic ulcer).
Option (3) Kidney — an organ of the body, which filters the blood and makes urine. It is not a disease, so the kidney is the odd one out.
Option (4) Anaemia — a disease: too little haemoglobin or too few red blood cells in the blood.
