To answer this question, review your notes and see figure $14\mathrm{.}12$ from Reading #$4$

a$.$ Draw the orbital energy diagram $($just the relative energy levels$)$ for the ground state of molecule $B$ from question $1.$

b$.$ Populate the diagram you drew in part a with the electrons from molecule B$.$

c$.$ Identify the HOMO and LUMO

d$.$ Redraw the orbital energy diagram with the electrons after the molecule has absorbed UV$-$visible light. The is called the excited state.
