Question
**Question 3:** What classification of monosaccharide is shown here?

**Options:**
A. D-aldohexose  
B. D-ketohexose  
C. D-ketopentose  
D. D-aldopentose  
E. L-aldohexose  
F. L-ketohexose  
G. L-aldopentose  
H. L-ketopentose  

**Diagram Explanation:**

The diagram is a structural representation of a monosaccharide. It consists of a backbone with four carbon atoms and one additional carbon extending from a carbonyl group (C=O) at the top. The structure displays the following groups attached:

- An aldehyde group (CHO) at the top.
- Hydroxyl groups (OH) and hydrogen atoms (H) alternating on either side of the carbon chain.
- A terminal CH₂OH group at the bottom.

This structure suggests it is an aldose sugar, typically a pentose due to the presence of five carbon atoms.
