Define "sexual assault" under Texas Penal Code.

Under the Texas Penal Code, "sexual assault" is defined specifically as the act of intentionally or knowingly causing physical contact with another person in a sexual manner without that person's consent. This definition emphasizes the importance of the lack of consent and the intentional aspect of the act, which makes option B the most accurate representation of what constitutes sexual assault in Texas law.

This definition highlights not only the act itself but also the necessity that consent must be absent for the act to qualify as sexual assault. Other options, while they may touch on aspects related to sexual misconduct, do not fully encapsulate the legal definition of sexual assault as clearly and comprehensively as option B does. For instance, engaging in sexual acts with minors, as mentioned in one option, relates to a specific statute concerning minors and statutory rape, but it does not cover broader incidents of sexual assault against individuals of any age without consent. Similarly, using threats to obtain sexual favors pertains more to coercion or extortion rather than the broader legal definition of sexual assault absent of consent.
