Solution
An acidic oxide is produced by the element C.
Explanation:
Carbon (C) is a non-metal, and non-metals typically react with oxygen to form acidic oxides. When carbon dioxide (CO2) dissolves in water, it reacts to produce carbonic acid (H2CO3). In contrast, sodium (Na) and calcium (Ca) are metals that form basic oxides, while hydrogen (H) forms water, which is a neutral oxide.
