Assertion (A) `D(+)-` Glucose is dextrorotatory in nature.
Reason (R) 'D' represents its dextrorotatory nature.

Options

A. Assertion and reason both are correct statements and reason explains the assertion.
B. Both assertion and reason are wrong statements
C. Assertion is correct statement and reason is wrong statement.
D. Assertion is wrong statement and reason is correct statement.

Explanation

To analyze the given assertion and reason, we will break down each statement and evaluate their correctness.

### Step 1: Evaluate the Assertion (A)
The assertion states that "D(+)-Glucose is dextrorotatory in nature."

- **Explanation**: D(+)-Glucose is indeed known to be dextrorotatory, which means it rotates plane-polarized light in a clockwise direction. This is a well-established characteristic of D(+)-Glucose.

- **Conclusion**: The assertion is **True**.

### Step 2: Evaluate the Reason (R)
The reason states that "'D' represents its dextrorotatory nature."

- **Explanation**: The letter 'D' in D-glucose does not specifically denote dextrorotatory nature. Instead, it is part of a nomenclature system that distinguishes between different forms of sugars (D and L forms). The dextrorotatory nature is actually indicated by the '+' sign (or sometimes 'd'), while 'D' refers to the configuration of the molecule based on the orientation of the hydroxyl group on the penultimate carbon atom.

- **Conclusion**: The reason is **False**.

### Final Evaluation
- Since the assertion is true and the reason is false, the overall statement is that the assertion is correct, but the reason is not.

### Summary
- Assertion (A): True
- Reason (R): False
