Carbides
Nitrides
Oxides
Sulfides

The correct answer is: Oxides

Oxides are compounds that contain oxygen combined with another element, excluding silicon. In this case, the correct answer is C because oxides are the only option listed that specifically involve oxygen and a different element. Carbides consist of carbon combined with a less electronegative element. Nitrides involve nitrogen combined with other elements. Sulfides are compounds containing sulfur with another element. Therefore, the correct answer is C (Oxides) as it is the only compound in the list that fits the description provided in the question.
