(B) Homologous organs are those that share a common evolutionary origin and structural plan,even if they perform different functions.$I.$ Hands of man and wings of bat are homologous as they share the same pentadactyl limb structure.$V.$ Forearm of human and forelimbs of horse are also homologous,sharing the same skeletal arrangement (humerus,radius,ulna,carpals,metacarpals,and phalanges).$II.$ Wings of bat and wings of cockroach are analogous (different origin,similar function).$III.$ Wings of bird and wings of butterfly are analogous.$IV.$ Fins of fish and forelimbs of horse are not considered homologous in the same structural sense as the others.Therefore,the correct pair is $I$ and $V$.
