Sugar ‘X’

A.  is found in honey

B.  is a keto sugar
C.  exists in α and β – anomeric forms.
D.  Is laevorotatory.

‘X’ is :

The correct answer is D-Fructose.

Let us evaluate each of the given statements in the question for Sugar 'X':

Statement A: is found in honey
D-Fructose is also known as fruit sugar or levulose and is abundantly found in honey, sweet fruits, and root vegetables. Along with glucose, it is one of the main components of honey.

Statement B: is a keto sugar
D-Fructose is a monosaccharide containing six carbon atoms with a ketone functional group at the C-2 position. Thus, it is classified as a ketohexose (a keto sugar).

Statement C: exists in α and β - anomeric forms
In solution, D-Fructose undergoes cyclization where the hydroxyl group at C-5 (or C-6) reacts with the keto group at C-2 to form a cyclic hemiketal structure. This reaction creates a new chiral center at the C-2 carbon (the anomeric carbon), giving rise to two stereoisomeric forms: $\alpha$-D-fructofuranose and $\beta$-D-fructofuranose. Therefore, it exists in $\alpha$ and $\beta$ anomeric forms.

Statement D: Is laevorotatory
Fructose rotates the plane of polarized light to the left (counterclockwise), which makes it strongly laevorotatory. It has a specific rotation of approximately -92.4°. Because of this property, it is also called levulose.

Since Sugar 'X' satisfies all the given conditions (found in honey, is a keto sugar, has $\alpha$ and $\beta$ anomers, and is laevorotatory), 'X' is D-Fructose.
