Solution
The correct option is A Polio Poliomyelitis, often known as polio or infantile paralysis, is an infectious disease caused by the poliovirus which affects the brain and spinal cord. In about 0.5 per cent of cases, there is muscle weakness resulting in an inability to move. Poliomyelitis results from viral invasion of the motor neurons of the anterior horn cells (dorsal horn cells) of the spinal cord, which are responsible for the movement of muscles.
