(B) -fructose is a ketohexose. Its open-chain structure has a ketone group at $C-2$. The configuration at the chiral centers $C-3, C-4,$ and $C-5$ is as follows: At $C-3$,the $-OH$ group is on the left. At $C-4$,the $-OH$ group is on the right. At $C-5$,the $-OH$ group is on the right (which determines the $D$-configuration). Comparing this with the given options,the structure in option $B$ matches the correct Fischer projection of $D$-fructose.

The Fischer projection formula of $D-(-)$-fructose is:
