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 $C$

$\varnothing$

Option A
Option B
Option C
Option D

Solution

$A \not\subset \varnothing ,B \not\subset \varnothing ,C \not\subset \varnothing $

Therefore, $\varnothing$ cannot be the universal set for the sets $A , B$ and $C$.
