Organize the following expressions from greatest to least by number of terms:
I: 6x2
II: 18x2 + 5ab − 6y
III: 8a − 5
IV: 4x3 + 3x2 − x − 4
A: II, III, IV, I
B:IV, II, I, III
C: III, II, I, IV
D:IV, II, III, I
I think its D because the last one seems to have the most terms and it looks right but idk
