Answer:

B.... wings of pigeon and bat

Answer 2

Forelimbs of cow, a duck and a lizard are homologous

Explanation:

Homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor. These structures do not have to look exactly the same, or have the same function.

Forelimbs of cow, a duck and a lizard are homologous as cow use the forelimbs for walking, duck for flying and lizard for climbing.
