B.
Only I and II
C.
Only II, III, and IV
D.
Only I, II, and III​

Answer 1

Answer:

option :-A is right because as we know ionization energy =amount of energy required to remove an electron form gaseousisolated atom . And as we move down a group no.of shells increases and the power of nucleus on outermost electrons decreases and because of this we can easily remove the electron ..by applying little amount of energy .
