(A) The given Fischer projection of sugar $[X]$ is $D-$mannose. In $D-$mannose,the $-OH$ groups at $C-2$,$C-3$,$C-4$ and $C-5$ are on the left,left,right and right respectively in the Fischer projection. When converting to the Haworth structure,groups on the left side of the Fischer projection are placed above the ring,and groups on the right side are placed below the ring. For $\alpha -D-$mannopyranose,the $-OH$ group at the anomeric carbon $(C-1)$ is below the ring. Thus,the correct Haworth structure corresponds to option $A$.

The correct representation in $6-$membered pyranose form for the following sugar $[X]$ is
