if the following mRNA strand were produced during transcription what amino acids would be found in the protein GGCUACGGGCAUCAC
ioda

The correct answer to your question is B. Glycine-Tyrosine-Glycine-Histidine-Histidine.

You can find this by taking groups of codons starting with the first group (GGC). GGC is located under Glycine so Glycine will therfore be an amino acid found in the protein. Continue doing this with the next codons to come up with the answer.

I hope this isn't too late and still helps!
