(C) Metallic character is defined as the tendency of an element to lose electrons. Metallic character increases as we move down a group and decreases as we move from left to right across a period. The positions of the given elements in the periodic table are: $P$ (Group $15$,Period $3$) $Si$ (Group $14$,Period $3$) $Mg$ (Group $2$,Period $3$) $Na$ (Group $1$,Period $3$) $Be$ (Group $2$,Period $2$) Comparing these,$P$ is the least metallic (non-metal),followed by $Si$ (metalloid). Among the metals,$Be$ is less metallic than $Mg$ (since $Be$ is in Period $2$ and $Mg$ is in Period $3$ of the same group). $Na$ is the most metallic as it is in Group $1$. Thus,the correct order of increasing metallic character is: $P < Si < Be < Mg < Na$.

The correct order of increasing metallic character of $Na$,$Be$,$P$,$Mg$ and $Si$ is:
