(A) Metallic character increases down a group and decreases along a period as we move from left to right.In the periodic table,the positions are:$Na$ (Group $1$,Period $3$)$Mg$ (Group $2$,Period $3$)$Be$ (Group $2$,Period $2$)$Si$ (Group $14$,Period $3$)$P$ (Group $15$,Period $3$)Comparing these,$Na$ is the most metallic and $P$ is the least metallic.The correct order of increasing metallic character is: $P < Si < Be < Mg < Na$.
