MCQ
If $A = \{1, 2, 3, 4, 5, 6\}, B = \{2, 4, 6, 8\},$ then $A - B$ will be:
  • A
    $\{1, 3, 5, 8\}$
  • ✓
    $\{1, 3, 5\}$
  • C
    $\{1, 2, 3, 4, 5, 6, 8\}$
  • D
    $ \{\}$
✓

Answer

Correct option: B.
$\{1, 3, 5\}$
Given, $A = \{1, 2, 3, 4, 5, 6\}$ and $B = \{2, 4, 6, 8\}$
$A - B$ means $A$ contains the element which is not present in $B.$
Thus, $A − B = \{1, 3, 5\}$
