Out of the following statements, which one is false?
A. Every transition metal, with the exception of scandium, forms ionic MO oxides.
B. Sc2O3 to Mn2O7 exhibit the highest oxidation number, which corresponds to the group number in transition metal oxides.
C. Basic character gets better in V2O3, V2O4, and V2O5.
D. When V2O4 dissolves in acid, three VO4 salts are produced.
E. While Cr2O3 is amphoteric, CrO is basic.
Select the right response from the list of choices below:
(1) Just A and E; (2) B and D; (3) C and D; (4) B and C alone<end_of_turn>

Statements C and D are incorrect.
- All reactions are transitions of metals except Sc from MO oxides which are ionic.
- The highest oxidation number corresponding to the group number in transition metal oxides in
attained in Sc2O3 to Mn2O7.
- Acidic character increases from V2O3 to V2O4 to V2O5.
- V2O4 dissolves in acids to give VO2+
- CrO is basic but Cr2O3 is amphoteric<end_of_turn><eos>
