Which of the following is an example of a need?

A need is something that is essential for survival and well-being. In this context, water is classified as a need because it is vital for human life; without it, a person cannot survive. Water is necessary for hydration, basic physiological functions, and overall health, making it fundamentally important.

In contrast, the other options represent wants or desires rather than essential needs. Soft drinks, chocolate, and furniture can enhance quality of life but are not critical for survival. They are items that individuals may desire for enjoyment, convenience, or comfort, but they do not fulfill the basic requirements for existence in the same way that water does.
