(c) Arsenic
(d) Caesium​

Answer 1

Answer:

(c) Arsenic

Explanation:

when we go in period from left to right electronegativity increase... and when we go in group from up to down it will decrease so Na and Cs are more electropositive not negative

rest gallium and Arsenic... gallium from group 13 and arsenic from 15 thus As will be more electronegative among them

Answer 2
