Explanation
In the image you can see four characters, a doctor and a nurse, a patient on a stretcher and a man with a noble appearance. The doctor is holding a large syringe that is inscribed "prohibition" to vaccinate the patient representing the "American population." This image represents "The noble experiment" a ban imposed on the population of the United States from 1920 to 1933 with the aim of preventing domestic abuse and family abandonment. This complements very well with the introductory text that accompanies it because this allows a very clear understanding of the reason for this cartoon and the statements that are in it because they are not very clear. Therefore, the correct answer is B. It helps to clarify the meaning of the cartoon by explaining the term "The Noble Experiment"
