Which of the following correctly represents the classification of glucose in terms of its structure?

Glucose is classified as an aldose and a hexose based on its structural characteristics. As an aldose, glucose contains an aldehyde group (-CHO) at one end of its carbon chain, which is a defining feature of aldoses. This aldehyde group is responsible for its classification as an aldose sugar.

Additionally, glucose has six carbon atoms in its structure, which classifies it as a hexose. The term "hexose" includes all monosaccharides that contain six carbon atoms, and glucose fits this category perfectly, having the chemical formula C6H12O6.

In summary, glucose is correctly identified as both an aldose and a hexose due to the presence of the aldehyde functional group and the six carbon atoms in its molecular structure.
