• B. A-III, B-IV, C-I, D-II
• C. A-III, B-IV, C-II, D-I
• D. A-II, B-I, C-IV, D-III

Answer 1

Answer: (B)

A-III, B-IV, C-I, D-II

Answer 2

1. Principal quantum number ($n$) gives the size of the orbital.

2. Azimuthal quantum number ($l$) gives the shape of the orbital.

3. Magnetic quantum number ($m$) gives the orientation of the orbital.

4. Spin quantum number ($m_s$) gives the orientation of the spin of the electron.
