Name the three body parts of the victim that can be violated by a rapist.

The correct answer identifies the three primary body parts that can be violated in a sexual assault scenario: anal, vaginal, and oral. This choice encompasses the different forms of sexual assault that occurring through penetration or the violation of these anatomical areas.

The anal and vaginal areas are specifically targeted due to their anatomical relevance in instances of sexual violence, while the oral cavity is included as it can also be subjected to violations. The comprehensiveness of this choice highlights the various methods through which sexual assault can occur, thereby giving a clearer understanding of the scope of crimes relating to sexual violence.

The other options either include body parts that are not typically associated with sexual violation or do not fully encompass the common scenarios that can arise in cases of sexual assault. Therefore, option A stands out for its accuracy in representing the bodily areas involved in such offenses.
