Which term describes a type of carbohydrate primarily consisting of sugar?

The correct choice is a term that identifies carbohydrates that are primarily made up of sugar and typically consist of one or two sugar units. Simple carbohydrates are known for their quick and easy digestibility, often delivering a rapid source of energy. Common examples include glucose, fructose, and sucrose, which are found in foods like fruits, honey, and table sugar.

In contrast, complex carbohydrates consist of long chains of sugar molecules that take longer to break down, providing sustained energy over time. Polysaccharides, being a type of complex carbohydrate, include starches and fibers, which are not primarily composed of simple sugars but rather consist of many sugar units linked together. The term "sugar" itself is more general and can refer to both simple and complex forms of carbohydrates but does not specifically capture the distinction made between types of carbohydrates such as simple and complex. Hence, the term that accurately denotes carbohydrates primarily consisting of sugar is simple carbohydrate.
