Figure 1 Shown Below Is the Structure of Caffeine in the Centre

Figure 1
Shown below is the structure of caffeine in the centre and two different resonance states I and II with lone pairs and formal charges omitted.
-Referring to Figure 1,which of the following best describes the resonance states I and II?

A) I is more stable than II because the formal negative charge is on a more electronegative atom.
B) I is more stable than II because all the atoms follow the octet rule.
C) II is more stable than I because the formal negative charge is on a more electronegative atom.
D) II is more stable than I because all the atoms follow the octet rule.
