(A) In noble gases,as we move down the group,the number of electronic shells increases,which leads to an increase in the atomic size. Due to the increase in atomic size and the shielding effect,the attraction between the nucleus and the valence electrons decreases. Consequently,the energy required to remove an electron,known as the $IE$ (Ionization Energy),decreases.
