In evolution the studies can be made at molecular level. For example, the proteins present in the blood of man and ape are similar. The base sequence in nucleic acids and amino acids sequence in proteins of related organism is alike. These are the examples which are specifically referred to in

Solution

The correct option is B Molecular homology
The genetic codons are universal in all organisms this suggests the common ancestry of all organisms. While the presence of ABO blood type blood grouping in human and apes suggest their common ancestry. Both of the above examples are evidence of Evolution from genetics and biochemistry showing homology in ancestors and present-day evolved species.
So, the correct answer to the question is 'Molecular homology'.
