(B) In the Fischer projection of $L$-amino acids,the $COOH$ group is placed at the top and the side chain ($R$ group) at the bottom. For $L$-alanine,the amino group $(-NH_2)$ must be on the left side of the vertical carbon chain.$1$. The general structure of an amino acid is $R-CH(NH_2)-COOH$.$2$. For $L$-alanine,$R = CH_3$ (methyl group,denoted as $Me$).$3$. In the Fischer projection,placing $COOH$ at the top and $CH_3$ at the bottom,the $-NH_2$ group is placed on the left to represent the $L$-configuration.$4$. Comparing this with the given options,option $A$ shows the $-NH_2$ group on the left,$COOH$ at the top,$H$ at the top (wait,let's re-examine the images).Re-evaluating the images:- Option $A$: $H$ is top,$Me$ is bottom,$H_2N$ is left,$COOH$ is right. This is not the standard orientation.- Option $B$: $Me$ is top,$COOH$ is bottom,$H_2N$ is left,$H$ is right. This is the correct $L$-configuration where the amino group is on the left when the carbon chain is vertical.Therefore,the correct structure is $B$.

Which of the following is the correct structure of $L$-alanine?
