Which of the following refers to unlawful touching of another person without consent?

The term that refers to unlawful touching of another person without consent is battery. This legal concept is integral to understanding personal injury law, as it highlights how one individual's physical interaction with another can have legal ramifications when it occurs without permission. Battery does not require the intention to harm; rather, it focuses on the non-consensual nature of the physical contact.

In contrast to battery, slander and libel pertain to defamation. Slander involves verbal statements that harm someone's reputation, while libel refers to written statements that achieve the same outcome. Both forms of defamation do not involve physical touching, but rather the communication of harmful statements. Thus, they fit into a different category of legal issues concerning reputation rather than physical safety.
