The hypothesis is that higher anti-HPV antibody levels provide greater protection from HPV-related cancers compared to lower levels. Therefore, the study requires participants who have been vaccinated against HPV. Group A consists of 100 vaccinated adult males and 100 vaccinated adult females, making them the ideal choice for the experimental group in the study. Group B has only 100 vaccinated adult males, which is not ideal as there is no control group. Group C is not an even distribution of males and females and could potentially skew the results. Group D consists of unvaccinated individuals, which does not fit with the requirements of the study.
