The Correct Option is C

Solution and Explanation

Homologous organs, are those organs which have a common fundamental anatomical plan and similar embryonic origin but perform varied, functions. Forelimbs of cat, lizard used in walking, forelimbs of whale used in swimming and forelimbs of bats used in flying are the example for homologous organs. All are the modified forelimbs, with the same type of bones. They have become different due to the adaptations to different habitat.

Evolution

Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
