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?

Evaluating the statements about biology and medicine: 1. Statement 1 is correct. The Femur, or thigh bone, is the longest, largest, and strongest bone in the human body. 2. Statement 2 is correct. Cholera is an infectious disease characterized by severe watery diarrhea, which is caused by the bacterium Vibrio cholerae. 3. Statement 3 is incorrect. 'Athlete's foot' (tinea pedis) is a common fungal infection of the skin on the feet, not a disease caused by a virus. Given the answer key is 'B' (2 and 3), there is a contradiction as statement 1 is correct and statement 3 is incorrect. Statement 2 is correct. *Following the answer key 'B' requires accepting statement 3 as correct (caused by virus) and statement 1 as incorrect (femur not longest bone), both of which are factually wrong.* A correct answer based on facts would be '1 and 2' (A).
