$(i)$ Increases continuously; $(ii)$ Decreases continuously

(A) As we move down a group in the periodic table,the number of shells increases,which leads to an increase in the atomic radius. As we move from left to right across a period,the effective nuclear charge increases while the number of shells remains the same,which leads to a decrease in the atomic radius.

A
$(i)$ Increases continuously; $(ii)$ Decreases continuously
B
$(i)$ Decreases continuously; $(ii)$ Increases continuously
C
$(i)$ Increases continuously; $(ii)$ Decreases up to the group $IV$ and then increases up to the end of the period.
D
$(i)$ Decreases continuously; $(ii)$ Decreases up to the group $IV$ and then increases up to the end of the period.
