Dominant Alleles
Dominant alleles are those which are expressed in an individual, regardless of whether they are in a homozygous or heterozygous state. In other words, if an individual has at least one copy of the dominant allele, it will be expressed.
Homozygous and Heterozygous States
Alleles can exist in two states - homozygous and heterozygous. Homozygous individuals have two copies of the same allele, while heterozygous individuals have one copy of each allele.
Dominant Alleles in Homozygous State
If a dominant allele is present in a homozygous state, it means that both copies of the gene are dominant. This results in the expression of the dominant trait in the individual. For example, if an individual has two copies of the dominant allele for brown eyes (B), they will have brown eyes.
Dominant Alleles in Heterozygous State
If a dominant allele is present in a heterozygous state, it means that the individual has one copy of the dominant allele and one copy of the recessive allele. In this case, the dominant allele is still expressed, and the individual will have the dominant trait. For example, if an individual has one copy of the dominant allele for brown eyes (B) and one copy of the recessive allele for blue eyes (b), they will have brown eyes.
Conclusion
In conclusion, dominant alleles are expressed in both homozygous and heterozygous states. This means that if an individual has at least one copy of the dominant allele, they will express the dominant trait.

The homozygous combination is the condition in which both the alleles are similar, i.e. a gene has identical alleles on both the chromosomes( homologous chromosomes).
On the other hand, the heterozygous combination is the one in which a gene has dissimilar alleles on both the chromosomes and in such a situation the allele that gets expressed is the dominant one whereas the allele that gets suppressed is the recessive one . so
option C is right answer
