Solution

The correct option is A A- 1, B- 3, C- 2, D- 4
Fossils are the preserved remains of primitive organisms that serve as proof of evolution and support the view that living organisms are under constant evolution (A-1).
Embryology follows biogenetic law and studies similarities and dissimilarities between early developmental stages of animals as well as different developmental stages of same animal to establish evolutionary relations among them (B-3).
Cytology studies with structure, reproduction, function and complete life cycle of cell of an organism and reflects the basic relationship among different organisms (C-2).
DNA is the genetic material that carries genetic information regarding corresponding amino acid sequence of proteins. Accumulation of differences in their genomes and thus, amino acid sequence of their proteins parallels divergent evolution of species while conservation of DNA sequences leads to convergent evolution (D-4).
