Which of the following words best represents someone who is lazy or neglectful?

The term that best represents someone who is lazy or neglectful is "truant." It refers specifically to a person who stays away from a place, particularly school, without permission, often implying neglect of responsibilities and a lack of diligence. This word captures the essence of someone who fails to fulfill their obligations, making it a fitting choice for describing laziness or neglect.

In contrast, the other options represent positive qualities. "Industrious" indicates hard work and diligence, "diligent" points to careful and persistent effort in doing something, and "eager" describes someone who is enthusiastic and keen to engage in activities. Each of these words conveys an attitude of commitment and effort, which is opposite to the concept of laziness or neglectfulness.
