The good electron loser elements belongs to group:

Explanation

Option A is correct since group 1A atoms lose their electron easily because they are large and ionization energy decreases down the groupOption B is incorrect since group 2A will lose electrons less easily than group 1A atoms as they are comparatively smaller than group 1A atoms due to greater nuclear charge across the same period Option C is incorrect since group 3A will lose electrons less easily than even group 2A atoms as they are comparatively smaller than group 2A atoms due to greater nuclear charge across the same period Option C is incorrect since group 4A will lose electrons less easily than even group 3A atoms as they are comparatively smaller than group 3A atoms due to greater nuclear charge across the same period
