    The correct answer is option D.

    Explanation:

    The process of translation, that is, synthesis of proteins takes place until the occurrence of the termination process. The termination takes place when the ribosome encounters a stop codon. These are UAG, UAA, and UGA. As there are no molecules of tRNA, which can identify these codons, the ribosome determines that the process of protein synthesis is complete. The formed protein then get discharged and the complex of translation move away from each other.
