The answer to the presented problem together with the options available would be A. gene.
A gene is the basic unit of heredity in a human being. This is where all information about the human is stored and is transferred from the parents to the offspring. Characteristics and behaviours become redeeming qualities to a specific line of heredity. With this, studies have paved way to understanding more about evolution and the past. This might be used to enhance human capabilities and make us more superior to any other race.
