Answer:
Cys
Explanation:
tRNA or transfer RNA has an anticodon which base pairs with the complementary codon on mRNA or messenger RNA. It brings the amino acid corresponding to the codon present on mRNA. Since the tRNA here has anticodon ACG in 3' to 5' direction, the complementary codon on mRNA will be UGC in 5' to 3' direction. UGC codon corresponds to Cysteine amino acid which is abbreviated as Cys in three letters.
The answer is C: a pollutant.
