Explanation:

<em>The correct option would be that mRNA interacts with ribosomes in the cytoplasm.</em>

<u>During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon</u>.
