Carbohydrates are made of...

Explanation:
Carbohydrates are composed of carbon, hydrogen, and oxygen in a roughly 1:2:1 ratio, often written as (CH2O)n. A familiar example is glucose, C6H12O6, which shows all three elements in that same pattern. That’s why the correct choice lists C, H, and O—the elements that define carbohydrates. Choices that include nitrogen or omit hydrogen don’t fit the standard composition of carbohydrates.
