Results in absence of the gene product - is the best answer since an altered gene product will be produced.

The mutation shifts the gene product to a new function so the original gene product is absent from this allele. Any heterozygote containing the new allele along with the original wild type allele will express both products. Genetically this will define the mutation as a dominant.

B) results in absence of the gene product
