(A) As the given elements $Li$,$Be$,$C$,and $N$ belong to the same period,i.e.,the $2^{nd}$ period,the atomic radius decreases on moving from left to right across the period.This decrease occurs because the effective nuclear charge increases while the number of shells remains constant.Therefore,$Li$ (Lithium),being the leftmost element in the $2^{nd}$ period,has the largest atomic radius among them.
