Answer:

Option a. met3, Met3p, MET3 is correct answer

"An investigator is studying mutants in methionine synthesis. The _met3_ mutants are unable to ATP sulfurylase, also known as _Met3p_. This protein is the product of the _MET3_gene. "

Explanation:

MET3 encodes ATP sulfurylase, which is a catalyst of first step of the sulfur assimilation pathway. This pathway results in the formation of hydrogen sulfide which is  a precursor in the biosynthesis of  cysteine, homocysteine, and methionine.
