Answer
Based on the evaluations above, the correct identification of the properties of the oxides in order is:
Na ext{ }O: Basic oxide
Mg ext{ }O: Basic oxide
Al ext{ }O ext{ }3: Amphoteric oxide
P ext{ }O ext{ }10: Acidic oxide
SO ext{ }3: Acidic oxide.
Thus, the correct choice aligning with these classifications is option C.
