Step 1: Understanding Maltose.
Maltose is a disaccharide consisting of two glucose molecules. The two glucose units are connected by an -glycosidic bond. Step 2: Analyzing the linkage.
In maltose, the glycosidic linkage between the two glucose units is . This is a key feature of maltose. Thus, the correct answer is (D).

Concept:
Different sugars are used in daily life, and their chemical identities vary.
Explanation:

The sugar commonly used in homes is table sugar.
Table sugar is chemically known as sucrose ( ).
It is a disaccharide made of glucose and fructose units.
About Glucose:

Glucose is a monosaccharide ( ).
It is found in fruits, honey, and blood sugar.
It is not the common household sugar.
Conclusion:
Since household sugar is sucrose and not glucose, the statement is incorrect.
