Option A
Option B
Option C
Option D

Solution

$K$ is in group $1 .$ Therefore, the oxide will be $K _{2} O$

$C$ is in group $4 .$ Therefore, the oxide will be $CO _{2}$

$Al$ is in group $3 .$ Therefore, the oxide will be $Al _{2} O _{3}$.

$Si$ is in group $4 .$ Therefore, the oxide will be $SiO _{2}$

$Ba$ is in group $2 .$ Therefore, the oxide will be $BaO$.
