The correct answer is A. the Most reactive non-metals.In the first place, if someone knows how to read the periodic table he would have no confusion in deciding whether the group 7 has metals or non-metals. Group 7 contains metals not so, basically, we can easily cancel two metal options.In the second place of the group 7 non-metals are the most reactive metals because they only need one electron to complete their valence shell and become stable.
