What scenario indicates the absence of consent in a sexual encounter?

The scenario that indicates the absence of consent is when one party is intoxicated and passes out. Consent requires clear and conscious agreement from all participants involved in a sexual encounter. When someone is incapacitated due to intoxication, they cannot provide coherent and informed consent, making any sexual activity that occurs while they are unconscious invalid. This principle is vital in discussions of consent as it underscores the need for all parties to be fully aware and capable of making decisions regarding their own bodies.

In contrast, the other scenarios demonstrate situations in which consent is present or implied, as they involve mutual understanding and clear communication between consenting parties.
