Correct answer: C. C
- A. A
- B. B
- C. C
- D. D
Explanation
If more than one degenerate orbitals are available then electrons go one by one with same spin. In option C th electrons occupy the degenrate orbitals separately but the spin of electron is different whereas it should be the same as the other two degenerate orbitals.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
