Which of the following describes items necessary for sustaining a human being at an appropriate living standard?

The term "necessaries" refers to items that are essential for maintaining a basic standard of living. This includes fundamental needs such as food, clothing, shelter, and healthcare, which are crucial for survival and well-being. "Necessaries" implies the minimum requirements that allow individuals to function and thrive in society, ensuring their health and safety.

On the other hand, luxury items represent products or services that provide comfort or pleasure but are not essential for survival. Common goods typically refer to resources that are shared among a community, while essentials is a more general term that could encompass various important items but may not specifically highlight the aspect of basic living standards as effectively as "necessaries." Therefore, "necessaries" is the most accurate term to describe what is required to sustain a human being at an appropriate living standard.
