You have discovered a protein that inhibits translation.When you add this inhibitor to a mixture capable of translating human mRNA and centrifuge the mixture to separate polyribosomes and single ribosomes, you obtain the results shown in Figure 7-39.Which of the following interpretations is consistent with these observations? Figure 7-39

The results show that the addition of the inhibitor causes a decrease in the amount of polyribosomes and an increase in the amount of single ribosomes. This suggests that the inhibitor is preventing the formation of more polyribosomes, indicating that it is inhibiting the rate of initiation of translation. Therefore, choice B is the best answer.
