Explanation
An optically active compound that rotates plane-polarized light counterclockwise is known as levorotatory, denoted by '(-)'. Therefore, all the given options (levorotatory, (-), and all of the above) are correct. The correct answer is 'all of above'.
which carbon is anomeric carbon in cyclic structure of glucose?

Explanation
The anomeric carbon in the cyclic structure of glucose is the carbon that was the carbonyl carbon (C=O) in the linear form of the molecule. For glucose, this is carbon 1 ( ext{C}_1). When glucose cyclizes to form a ring (either as an α or β anomer), ext{C}_1 becomes the anomeric carbon.
which carbon is anomeric carbon in cyclic structure of fructose ?

Explanation
The anomeric carbon in the cyclic structure of fructose is the carbon that was the carbonyl carbon (C=O) in the linear form of the molecule. For fructose, this is carbon 2 ( ext{C}_2). When fructose cyclizes to form a ring (either as an α or β anomer), ext{C}_2 becomes the anomeric carbon.
