Assertion: $β$ -glycosidic linkage is present in maltose.

Reason: Maltose is composed of two glucose units in which $C - 1$ of one glucose unit is linked to $C - 4$ of another glucose unit.

Both assertion and reason are wrong statements.

Solution

The correct option is C
Assertion is wrong statement and reason is correct statement.

Assertion

$α$ −glycosidic linkage is present in maltose. So, assertion is incorrect statement.

Reason
Maltose is composed of two $α - D$ -Glucose units in which $C - 1$ of one glucose unit (I) is linked to $C - 4$ of another glucose unit (II).

So, reason is the correct statement.

Hence, assertion is a wrong statement and reason is the correct statement.
