Answer: (a) O < C < B < Be < Li

Explanation:

(1) Atomic size increases down the group.

(2) Atomic size decreases across the period.

Li : group-1

Be : group-2

B : group-13

C: group -14

O : group-16

since, atomic radius decreses across the period. hence,

the correct order of increasing atomic radius is

O < C < B < Be < Li

therefore,

option (A) is correct.
