Option B nd D r correct electron affinity decrease (i.e with increase in electronegativity value) across a period while it increase (i.e with decrease in electronegativity value) down a group. Atomic radius also exhibits similar trend. So I think either of dem might b correct.

The right answer is D... Atomic radius which decrease as a rusult of screening effect...

The answer is B

both options b and d are correct because atomic radius and electron affinity decrease across the periodic table and increases down the period while ionization energy and electronegativity increases across the period and decreases down the group
