MCQ
If R is a relation from a non – empty set A to a non – empty set B, then
  • A
    $R \subseteq A \times B$
  • B
    $R=A \cap B$
  • C
    $R=A \cup B$
  • D
    $R=A \times B$
✓

Answer

(a) $R \subseteq A \times B$
Explanation: Let $A$ and $B$ be two sets. Then a relation $R$ from set $A$ to set $B$ is a subset of $A \times B$. Thus, $R$ is a relation from $A$ to $B \Leftrightarrow R \subseteq A \times B$.
