Explanation:
The most accurate evidence of an evolutionary relationship between two organisms is a) similarity in DNA
Similarity in DNA is the strongest evidence stating the evolutionary relationship acquired from a common ancestor.
If the similarity in DNA sequence is more then it co-relates with a more closer evolutionary relationship between the two given organisms.
The similarities between the molecules of the biological structure shows the evolutionary relationship signifying the evolutionary ancestory.
The comparison in DNA sequences shows that how come various species and organisms are interconnected with each other and have a specific relation.
Biogeographical distribution also provides us information regarding the evolution of various species on the earth.
Placing the DNA sequences in a row above each other and finding out comparison between the characters is an important aspect of comapring the two given DNA sequences.
