(D) To determine the $(R)$ or $(S)$ configuration,we assign priorities to the groups attached to the chiral center based on the Cahn-Ingold-Prelog $(CIP)$ rules: $1$. $-NH_2$ (priority $1$) $2$. $-COOH$ (priority $2$) $3$. $-CH_3$ (priority $3$) $4$. $-H$ (priority $4$) In the Fischer projection,if the lowest priority group $(-H)$ is on a horizontal bond,the configuration is reversed. Looking at option $(B)$: $-COOH$ (top,$2$),$-NH_2$ (right,$1$),$-CH_3$ (bottom,$3$),$-H$ (left,$4$). The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is clockwise,but since $-H$ is on a horizontal bond,the configuration is $(S)$. Looking at option $(D)$: $-COOH$ (top,$2$),$-NH_2$ (right,$1$),$-CH_3$ (left,$3$),$-H$ (bottom,$4$). The sequence $1$ $\rightarrow 2$ $\rightarrow 3$ is clockwise. Since the lowest priority group $(-H)$ is on a vertical bond,the configuration is $(R)$.

Amongst the following amino acids,the $(R)$-enantiomer is represented by:
