What term is used to describe a lack of care or negligence?

The term that describes a lack of care or negligence is "lax." This word specifically conveys the idea of being careless or not strict, which leads to negligence or a failure to take proper precautions. When someone is lax, they are often not attentive to detail or responsibility, resulting in a casual or overly lenient approach to tasks or obligations.

In contrast, the other choices highlight qualities opposite to negligence. "Diligent" refers to being hardworking and attentive to detail, while "precise" indicates accuracy and exactness, both of which imply a high level of care. "Meticulous" emphasizes extreme attention to detail and thoroughness, showcasing a proactive rather than negligent attitude. Therefore, "lax" is the only term that specifically captures the essence of negligence.
