Solution

The correct option is C They are uniparental in origin and do not take part in recombination
Wilson and sarich choose mtDNA for the study of maternal line inheritance while Y chromosomes were considered for the study of human evolution particularly male domain. Sequence of both mtDNA & Y chromosomes are considered for the study of human evolution because they are uniparental in origin. mtDNA is inherited along with the maternal cytoplasm and Y chromosome is inherited from father. So, they don't take part in recombination. In addition, mtDNA has a higher mutation than a nuclear DNA so that it is more useful for short term evolutionary studies.
So, the correct option is option C
