To account for the high electronegativity difference between hydrogen and fluorine, we reassign the orbital sites in HF in order to create an energy ladder that gives us a logical sequence for assigning electrons. Which statement about the reassigned orbital sites in HF is true?

A. There are two molecular orbital sites and two atomic orbital sites.
B. There are two molecular orbital sites and three atomic orbital sites.
C. There are four molecular orbital sites and one atomic orbital site.
D. There are five molecular orbital sites and zero atomic orbital sites.
