Strategy:
 Review the nature of oxides across a period. As we move from metals to non-metals (left to right), the character changes from strongly basic to amphoteric to acidic.

Step 1: Analyze Period 2 oxides
Elements: .
- : Alkali metal oxide  Strongly basic.
- : Group 2 metalloid-like metal  Amphoteric.
- : Group 13 non-metal  Weakly acidic.
- : Group 14 non-metal  Acidic.
- : Group 15 non-metal  Strongly acidic.

Step 2: Rank decreasing acidic nature
Decreasing acidic nature means starting f
