If A − B = ∅, then relation between A and B is: - Vidyadip

MCQ

If $A − B = ∅,$ then relation between $A$ and $B$ is:

A
$\text{A }\phi\text{ B}$
B
$\text{B}\cup\text{A}$
✓
$\text{A}\cap\text{B}$
D
$\text{A} = \text{B}$

✓

Answer

Correct option: C.

$\text{A}\cap\text{B}$

If $A$ and $B$ are disjoint it would mean $A$ is a null set. Otherwise $A$ and $B$ must be equal to $A ∩ B$ at least
