Answer #1

Plants, fungi, and prokaryotes all have cell walls. These cell walls were the result of the Option-B analogy. Analogy can be defined as the structural similarities that were originated independently in an organism to act the same purpose. In these organisms the basic function of the cell wall is to protect the cell from harmful conditions and provide structural support and rigidity. All of them have evolved independently thus it is an example of analogy.

Whereas Homology can be defined as the study of similar functions between different organisms, and then it helps in predicting their common ancestors, and genes will be predicted. So this is incorrect. Option -C, D, and E are similar to homology.
