Answer
Correct option: D.
All of these
d
Ceramics are inorganic , non-metallic, solid minerals. They come in a variety of forms, including silicates (silica, $SiO_2$ with metal oxides), oxides (oxygen and metals), carbides (carbon and metals), aluminates (alumina, $Al_2O_3$ with metal oxides) and nitrides.

The given ceramics are $B_4C$ (carbides), $SiC$ (carbides), $Si_3N_4$ (nitrides) and thus, none of these is an oxide . All of these are nonoxide ceramics.
