The correct option that shows the structure of the protein after digestion would be:
Differently colored spheres separated from each other. The colors of the spheres are the same as in the question.
After digestion, proteins are broken down into their constituent amino acids, resulting in the individual spheres (representing amino acids) being separated from one another. The spheres would still retain their original colors, representing the same amino acids present in the original protein structure.
So, the answer would be: Differently colored spheres separated from each other. The colors of the spheres are the same as in the question.
