Option 2 : Statement (ii) is true only

The correct answer is Statement (ii) is true only

Concept:

Atomic radius: It is the distance from the center of the nucleus to the outermost shell containing electrons.
Ionization energy: It is the energy required in removing an electron from an atom.
Electron Affinity: It is the energy change of the atom when an electron is added to a neutral gaseous atom to form a negative ion.

Explanation:

Ionization energy increases on going from left to right and from down to top.
Electron affinity increases on going from left to right and from down to top.
The atomic radius increases from right to left and top to bottom.
Hence only statement (ii) is true only.
