The mRNA sequence of the given amino acid sequence would be AUGAUCAGUCACGCAUAUG. This mRNA transcript will have a codon sequence of AUG-AUC-AGU-CAC-GCA-UAU-G. By referring to the genetic code chart, we can see that this codon sequence codes for Ile-Asp-Ser-Cys-His-Tyr. Among the given options, only option C has the same codon sequence as mentioned above. Hence, the correct answer is C.
