(a)
Interpretation:
From the given pair of elements, the one with more metallic character has to be predicted.
Concept introduction:
Metallic character and Non-metallic character:
Metallic character decreases in a period from left to right because the atomic size decreases and nuclear charge increases from going left to right in a period.
Non-metallic character increase in a period from left to right because the atomic size decreases and nuclear charge increases from going left to right in a period.
Metallic character increase in a group from top to bottom because the atomic size increase.
