In diploid organisms, having two homologues of each chromosome can be beneficial if one allele of a gene encodes a nonfunctional protein. can haploid organisms survive the presence of nonfunctional alleles?

Haploid creatures can not survive the nearness of nonfunctional alleles in light of the fact that there is just a single allele for the quality in every cell, and the nonfunctional allele has no other allele to cover it. I hope the answer will help you. 

The correct answer would be b
