Which of the following compounds include sugars and starches and consists of carbon, hydrogen, and oxygen?

The correct answer is a carbohydrate, which encompasses a wide variety of compounds that include sugars and starches. Carbohydrates are characterized by their composition of carbon, hydrogen, and oxygen atoms, typically following a general formula of ( \text{C}_n(\text{H}_2\text{O})_n ), where "n" represents the number of carbon atoms. This unique structure allows carbohydrates to serve essential roles in energy storage and supply for living organisms.

Sugars are simple carbohydrates composed of one or two sugar units (monosaccharides and disaccharides), while starches are more complex carbohydrates formed by long chains of glucose molecules (polysaccharides). Both forms are vital to biological processes, serving as primary energy sources for plants and animals.

The other options do not fit the description provided in the question. Chlorophyll, for example, is a pigment crucial for photosynthesis but does not include sugars or starches. Chlorosis refers to the yellowing of plant leaves due to nutrient deficiencies and is not a compound itself. Cambium is a layer of tissue in plants that contributes to growth but does not relate to the concept of sugars or starches. Understanding the definition and role of carbohydrates clarifies their significance in plant
