The example of oligosaccharide is A. Sucrose B. Glucose C. Ribose D. Cellulose

Sucrose
Glucose
Ribose
Cellulose

The correct answer is A. Sucrose.

Sucrose is a disaccharide, which is a type of oligosaccharide. It is made up of one glucose molecule and one fructose molecule. Sucrose is a common sweetener and is found in many foods, such as table sugar, honey, and fruit.

Glucose is a monosaccharide, which is the simplest type of sugar. It is the body’s main source of energy. Glucose is found in many foods, such as fruits, vegetables, and grains.

Ribose is a pentose sugar, which is a type of monosaccharide. It is found in RNA and DNA.

Cellulose is a polysaccharide, which is a type of carbohydrate that is made up of many sugar molecules. It is the main component of plant cell walls.

Here is a table that summarizes the information about each option:

| Option | Type of sugar | Description |
|—|—|—|
| Sucrose | Disaccharide | Made up of one glucose molecule and one fructose molecule. Common sweetener found in many foods. |
| Glucose | Monosaccharide | Body’s main source of energy. Found in many foods. |
