Best answer
Correct choice is (d) Limbs

Best explanation: Poliovirus generally affects the Motor Pathway of the neurons. It causes atrophy of muscles which affect the voluntary muscles of limbs and resulting in deformities. But, if the muscles of Diaphragm, Larynx and Pharynx are affected, it is always fatal.
