MCQ
If $A = \{1, 3, 5, B\}$ and $B = \{2, 4\},$ then:
  • A
    $4\in\text{A}$
  • B
    $\{4\}\subset\text{A}$
  • C
    $\text{B}\subset\text{A}$
  • ✓
    None of these.
✓

Answer

Correct option: D.
None of these.
$(4\not\in\text{A) }(4\not\in\text{A})$
$\{4\}\not\subset\text{A}$
$\text{B}\not\subset\text{}A$
Thus, we can say that none of these options satisfy the given relation.
