Answer: Option (A) is the correct answer.

Explanation:

When any neutral atom tends to gain an electron then it acquires a negative charge. This means that number of electrons has increased into the atom due to which its atomic radius will also increase.

On the other hand, when an atom tends to lose an electron then it acquires a positive charge. This means that number of electrons has decreases into the atom due to which its atomic radius will also decrease.

Thus, we can conclude that the radius of an anion is greater than the radius of its neutral atom.
