Assertion: all monosaccharides are reducing sugar
Reason : monosaccharides contain free aldehyde or free ketonic group
(a) If both assertion & Reason are true & the Reason is a correct explanation of the Assertion
(b) If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
(c) If Assertion is True but the Reason is False
(d) If both Assertion & Reason are false

Options

A. If both assertion & Reason are ture & the Reason is a correct explanation of the Assertion
B. If both Assertion & Reason ar True but Reason is not a correct explantation of the Assertion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false

Answer

To solve the question, we need to analyze the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states that "all monosaccharides are reducing sugars."
- **Definition**: Reducing sugars are sugars that can donate electrons or reduce another molecule. This property is typically due to the presence of a free aldehyde or ketone group.

### Step 2: Understand the Reason
The reason states that "monosaccharides contain free aldehyde or free ketonic group."
- **Explanation**: Monosaccharides, such as glucose and fructose, have either a free aldehyde group (in the case of aldoses) or a free ketone group (in the case of ketoses). This is what allows them to act as reducing sugars.

### Step 3: Analyze the Relationship
Now we need to determine if the reason correctly explains the assertion.
- Since all monosaccharides do indeed contain a free aldehyde or ketone group, they can act as reducing sugars. Therefore, the reason does provide a correct explanation for the assertion.

### Conclusion
Both the assertion and the reason are true, and the reason correctly explains the assertion.

### Final Answer
(a) If both assertion & Reason are true & the Reason is a correct explanation of the Assertion.
