Verified by Experts

The correct Answer is:
D
Baicity of oxides decreases in a period from left to right. `Na_(2)` O is basic oxide, `CO_(2) SiO_(2)` and `SO_(2)` are acidic oxides. Alternatively, oxides of metals `(e.g., Na_(2)O)` are basic, while oxides of non- metals `(SO_(2),SiO_(2) and CO_(2))` are acidic.
