The correct option is A Set 1: Metals and set 2: Non-metals
Metals are solids, and are good conductors of heat and electricity. They are malleable, ductile and sonorous in nature.
Most of the non-metals except bromine (liquid) are solids and gases.
From the table, set-1 elements (sodium, magnesium, iron, gold, and calcium) are metals, and set-2 elements (oxygen, chlorine, nitrogen, sulphur, and carbon) are non-metals.
