(A) $1$. $D$-glucose and $L$-glucose are enantiomers. To obtain the Fischer projection of $L$-glucose, we invert the configuration at all chiral centers $(C2, C3, C4, C5)$ of $D$-glucose.$2$. In $D$-glucose, the $-OH$ groups are at $C2$ (right), $C3$ (left), $C4$ (right), and $C5$ (right).$3$. In $L$-glucose, the $-OH$ groups are at $C2$ (left), $C3$ (right), $C4$ (left), and $C5$ (left).$4$. Cyclization of $L$-glucose involves the nucleophilic attack of the $-OH$ group at $C5$ on the carbonyl carbon $(C1)$.$5$. In the Haworth projection of $L$-sugars, the $-CH_2OH$ group at $C5$ points downwards. For the $\beta$-anomer, the $-OH$ group at the anomeric carbon $(C1)$ is on the same side as the $-CH_2OH$ group, meaning it also points downwards.$6$. Comparing this configuration with the given options, the structure of $\beta-L$-glucopyranose is correctly represented by option $(A)$.

The Fischer projection of $D$-glucose is given below. The correct structure of $\beta-L$-glucopyranose is:
