They cannot be found in plant-based foods.
B
They consist only of disaccharides such as sucrose and lactose.
C
They are the primary source of quick energy for the body.
D

Verified step by step guidance1
Understand the definition of complex carbohydrates: Complex carbohydrates are polysaccharides, which are long chains of monosaccharide units linked together by glycosidic bonds.
Recognize that complex carbohydrates are found in plant-based foods such as grains, legumes, and vegetables, contradicting the statement that they cannot be found in plant-based foods.
Differentiate complex carbohydrates from disaccharides: Disaccharides like sucrose and lactose are simple carbohydrates, not complex carbohydrates, as they consist of only two monosaccharide units.
Clarify the energy source role: Complex carbohydrates provide sustained energy due to their slower digestion and absorption, unlike simple carbohydrates which are a quick energy source.
Confirm the correct statement: Complex carbohydrates are indeed composed of long chains of monosaccharide units linked together, making this the accurate description.
