Correct Answer: Option D
Explanation

In a neutral atom, the atomic and ionic radius is the same, but many elements exist as anions or cations. If the atom loses its outermost electron (positively charged or cation), the ionic radius is smaller than the atomic radius because the atom loses an electron energy shell.

Yes ionic radius is only less than atomic radius for a metal.

There is an explanation video available below.
