Who is described as someone who cuts school or neglects their duties?

The term "truant" refers specifically to a person, often a student, who abandons their responsibilities or misses school without permission. This word has clear connotations of skipping class or failing to report for duty, which directly relates to the context of neglecting one's obligations. The other choices do not convey this meaning; for instance, "urbane" describes someone sophisticated and refined in manners, while "unprecedented" indicates something that has never happened before, and "unheralded" refers to something or someone that has not been recognized or praised. These words do not connect to the concept of neglecting duties or cutting school, making "truant" the most fitting option in this context.
