Consider the following statements: 1. Femur is the longest bone in the human body. 2. Cholera is a disease caused by bacteria. 3. ‘Athlete’s foot’ is a disease caused by virus. Which of the statements given above are correct?

Statement 1 is correct: the femur (thigh bone) is the longest and strongest bone in the human body, extending from the hip to the knee [2]. Statement 2 is correct: cholera is an infectious disease of the small intestine caused by the bacterium Vibrio cholerae and typically contracted from contaminated water or food, producing severe diarrhoea and dehydration [1]. Statement 3 is incorrect: “athlete’s foot” (tinea pedis) is a contagious fungal infection (dermatophytes) of the feet that thrives in warm, moist environments and is treated with antifungal agents, not a viral infection [3]. Thus the correct choice is option 1 (1 and 2).
