The trend in the metallic character is opposite to that of ionization energy. Metallic character increases down a group and decreases along a period as we move from left to right.

Left to right metallic character decreases

Top to bottom metallic character increases

\mathrm{\therefore Cl} (less metallic due to smaller size) \mathrm{< P < Si < Mg < Na} (more metallic due to large size)

Hence option 2 is correct.
