Answer:

(D) Carbohydrates can be divided into two groups, simple and complex.

Explanation:

The two major types of carbohydrates are: "Simple" and "Complex".  

Simple carbohydrates can be broken down and absorbed by the body quickly. Examples: glucose, sucrose. These carbohydrates quickly increase the  blood sugar levels of the body.

Complex carbohydrates are formed by long series of simple carbohydrates. There molecules are larger than simple carbohydrates. So, they are digested slowly and provide energy at a slower rate to the body. Examples: Starch and fiber present in wheat, pasta are complex carbohydrates.
