Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion : D (+) – Glucose is dextrorotatory in nature.

Reason : ‘D’ represents its dextrorotatory nature.

The D-L system corresponds to the configuration of the molecule and the spatial arrangement of its atoms around the chirality center. The D-L configuration is not to be confused with the d- l- naming which means dextrorotatory and levorotatory respectively. (+) and (-) notation corresponds to the optical activity of the substance, whether it rotates the plane polarized light clockwise (+) or counterclockwise (-). So, D(+) – glucose is dextrorotatory in nature but ‘D’ does not represent its dextrorotatory nature.
