Solution

The correct option is A
Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.

Statement 1: An element that has an electron configuration of $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 3 d^{3} 4 s^{2}$ is a transition element.
Statement 2: The transition elements from scandium to zinc are filling the 3d orbitals. Thus, such elements are characterized by incompletely filled penultimate d orbitals.
Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.
