D. None of the above

Explanation / Answer

1. C. Different cell types are different from each on the basis of Genetic Expression pattern

2. E. All of the above. The line of evidences considered as consistent with the theory of evolution by evaluation fossil records, biogeography, comparative analysis of anatomy and embroyology and also of genomics and molecular biology.

3. C. Both of the above. By comparing DNA and Protein sequences we can establishes the evolutionary links between the species.
