- A. 48
- B. 32
- C. 58
- D. 28
- E. 38
Explanation
According to federal text book, there are 38 transition elements. These d-block elements have 4 series i.e first outer transition series, second outer transition series, third outer transition series and fourth outer transition series.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
