Solution

The correct option is B Alleles

In the living organisms, characters are present in the form of pairs. Every character is under the control of a gene. So genes are present in pairs on two chromosomes at same locus. In a pair of genes, both genes are alternative forms with one another. It is called allele. These alleles may be similar (TT or tt) or contrasting (Tt).

So, the correct option is ‘Allele’.
