Comparing DNA might show more, since it would go down to the core.

Answer: The correct answer is -

B) molecular homology (comparing DNA).

DNA (deoxyribonucleic acid) is considered as the genetic material of living organisms, which is passed from one generation to the next generation that is from parents to their offspring.

By comparing the DNA sequence of two organisms (molecular homology), we can determine whether they are closely related or not.

If two organisms share genetic relatedness that is similarity in their DNA sequence, they are considered to be closely related.

Thus, option B) is the right answer.
