Solution
The correct option is A Region E
Region 'C' and 'E' contains 18 elements. These regions contain transition metals considering the two elements before 'A' show 1st period, Region 'C' shows the 4th period and region 'E' shows the 5th period. Here 'E' is closer to transition metals than 'D'. Therefore 'E' shows the transition metals of the 5th period.
