How many sugar links are present in monosaccharides?

Monosaccharides are the simplest form of carbohydrates and consist of a single sugar unit. Therefore, they contain only one sugar link, as they are not composed of multiple sugar molecules. This single sugar unit can include various types of monosaccharides, such as glucose, fructose, and galactose, but regardless of the type, they each maintain that singular structure. This is why the answer indicating a single sugar linked is correct, emphasizing the fundamental characteristic of monosaccharides as basic building blocks for more complex carbohydrates.
