Trafficking of proteins from the cytosol into different compartments in the euka

Question
Trafficking of proteins from the cytosol into different compartments in the eukaryotic cell relies on a signal sequence of amino acids in the polypepdtide. Some times this signal sequence is found at the carboxy end (C-terminus) of the polypeptide. If so, the mRNA sequence that codes for this amion acid signal sequence would be found:how and Why?
a) in the 5' UTR of the mRNA
b) in the 3' UTR of the mRNA
c) at the 5' end of the coding region of the mRNA
d) at the 3' end of the coding region of the mRNA
