Given the sets $A=\{1,3,5\}, B=\{2,4,6\}$ and $C=\{0,2,4,6,8\},$ which of the following may be considered as universal set $(s)$ for all the three sets $A$, $B$ and $C$
$\{ 0,1,2,3,4,5,6\} $
It can be seen that $A \subset\{0,1,2,3,4,5,6\}$
$B \subset\{0,1,2,3,4,5,6\}$
However, $C \not\subset \{ 0,1,2,3,4,5,6\} $
Therefore, the set $\{0,1,2,3,4,5,6\}$ cannot be the universal set for the sets $A , B ,$ and $C.$
