Question

If $A-B=\varnothing$, then relation between A and B is :

• A. $A\ne B$
• B. $B\subset A$
• C. $A\subset B$
• D. $A=B$

Answer 1

Answer: (C)

$A\subset B$

If A and B are disjoint it would mean A is a null set. Otherwise A and B must be equal to $A\cap B$ AT LEAST.

Hence option C is correct.
