A) The protons that give rise to the signal at 7 ppm are more shielded than the protons that give rise to the signal at 9 ppm. B) The protons that give rise to the signal at 7 ppm are less shielded than the protons that give rise to the signal at 9 ppm. C) The signal at 7 ppm is downfield from the signal at 9 ppm. D) The signal at 7 ppm is upfield from the signal 9 ppm. E) The resonance frequency of the protons that give rise to the signal at 7 ppm is larger than the resonance frequency of the protons that give rise to the signal at 9 ppm.
