Which of the Following Would Count as an Objection to Estes's

Which of the following would count as an objection to Estes's claim that mutual respect requires at least implicit expression of the voluntary participation of sexual partners in a sexual act?

A) Mutual respect requires not just that people communicate with their partners about consenting to sex, but also that they exhibit concern for each other's general well-being and attend to each other's sexual desires.
B) Mutual respect always demands explicit and not simply implicit expressions of consent because it is too easy for implicit forms of communication to lead to miscommunication and misunderstandings.
C) Mutual respect always demands explicit and not simply implicit expressions of consent because what matters ultimately is not the form of the communication itself but whether people have reasonable conscientious beliefs that reciprocal consent exists.
D) Mutual respect requires that people communicate not only about their consent, goals, and expectations about specific sex acts but also about their goals and expectations about their romantic relationships with their partners.
