Question

For two sets $\text{A}\cap\text{B = A}$ iff:

$\text{B}\subseteq\text{A}$
$\text{A}\subseteq\text{B}$
$\text{A}\not=\text{B}$
$\text{A}=\text{B}.$

✓

Answer

$\text{B}\subseteq\text{A}.$

Solution:

The union of two sets is a set of all those elements that belong to A or to B or to both A and B.

If $\text{A}\cup\text{B = A},$ then $\text{B}\subseteq\text{A}.$
