Which of the following is most likely the reason for this? Select the correct answer below: A. Each arsenic atom is sp2-hybridized. B. Arsenic has an unoccupied d-orbital. C. There is a single lone pair of electrons in arsenic's valence shell. D. There are two lone pairs of electrons in arsenic's valence shell.
