Best answer
Correct answer is (d) Sense

The best I can explain: All the other mutation lead to wild phenotype, so unless a genetic analysis is performed, they are indistinguishable. But in case of sense a stop codon is changed to a coding codon which has a serious phenotypic effect on the protein.
