Consider the filling of two electrons in the $p$ orbitals as shown in the following three figures



$\text { The correct statement is }$

• A

  Energies of the electronic configurations shown in Figures 1 and 2 are same, which are, however, lower than that of electrons in Figure 3.
• Correct answer
  B

  Energies of the above three different electronic configurations follow the order: $\mathrm{E}($ Figure 1) $ \lt \mathrm{E}($ Figure 2) $ \lt \mathrm{E}($ Figure 3).
• C

  The number of possibile of electron exchanges in both Figure 1 and Figure 2 is one.
• D

  $\text { Electronic configuration in Figure } 3 \text { is the most stable. }$

Hence, the correct answer is option: 'B'.
