Solution

The correct option is C Mitochondrail DNA
Hypothesis of ''African origin'' of man is based on the study of Mitochondrial DNA.
Mitochondrial DNA possesses several favorable characteristics, including large quantity in the cell, small genome size, haploid, maternal inheritance and extremely low probability of paternal leakage , higher mutation rate than nuclear DNA, and change mainly through mutation rather than recombination.
All these features make mt-DNA a useful and one of the most frequently used markers in molecular systematics and has been widely employed to address questions of genetic diversity, population structure, phylogeography and population evolution.
So, the correct option is 'Mitochondrial DNA'.
