Answer: Option (a) is the correct answer.

Explanation:

An atom with large atomic radius will be able to lose electrons more easily as the valence shell is away from the nucleus. Hence, force of attraction between the valence shell and nucleus will be less.

So, potassium being larger in size will be able to lose electrons easily as compared to bromine.

Hence, we can conclude that K will give up an electron more easily than Br.

The first choice is correct. K will give up electrons more easily, due to its smaller electronegativity.

Thus your answer is OPTION B
