Solution

The correct option is A Amongst isoelectronic species, smaller the positive charge on the cation, smaller is the ionic radius
Atomic radius of the elements decreases across a period from left to right due to increase in effective nuclear charge. On moving down a group. since, number of shells increases, so atomic radius increases.
Amongst isoelectronic species, ionic radius increases with increase in negative charge or decrease in positive charge.
