Explanation / Answer
answer : A and C
Explanation :
for A the first and 2nd ionization energies are slightly increase. but 3rd ionization energy is drastically increase.
for C also 3rd ionization energy is drastically increases.
so these two elements are the same group.
becuase remaining all are not similar to this trend.
