C Correct answer
Explanation

Polio is caused by the poliovirus which attacks the nervous system, specifically motor neurons in the spinal cord, causing paralysis. It does not affect the lungs. Pneumonia, bronchitis, and asthma are all respiratory conditions that directly affect lung tissue - pneumonia involves lung inflammation, bronchitis affects bronchial tubes, and asthma causes airway constriction.
