What is the relationship between the wing of a bird and the wing of a bat?

(A)They are homologous because they represent modified forms of a trait present in a common ancestor (forelimbs)
(B)They are analogous because while each carries out the same function (flight), this trait has arisen independently as a result of convergence
(C)There is no relation between the wings of bird and wings of bat
(D)Both (a) and (b)Correct
