Consider Gene A,which Has Two (2)alleles in the Population

Consider gene A,which has two (2) alleles in the population.A₄ codes for a mutated allele,which does not produce any protein;the associated phenotype is a disease state that reduces reproductive ability.A₂ is the normal allele and is dominant to the phenotype of A₄;the associated phenotype is not diseased.Based on this information,can natural selection eliminate the A₄ allele?

A) Yes,because it reduces the fitness of the bearer.
B) No,because it will remain "hidden" in heterozygotes.
C) Yes,because A₄ homozygotes can be eliminated.
D) No,because A₂ is dominant only in homozygotes.
