If $A = \{3, 4\}$ , $B = \{2, 4\}$ , $x \in A$ , $y \in B$ , the relation $x > y$ gives—

a $\{(3, 2), (4, 2)\}$
b $\{(3, 2), (4, 2), (4, 4)\}$
c $\{(3, 4), (4, 2)\}$
d $\varnothing$

ব্যাখ্যা

Taking each $x\in A$ and $y\in B$ with $x>y$ : from $x=3$ only $3>2$ holds, and from $x=4$ both $4>2$ holds (but $4>4$ is false). This gives exactly $\{(3,2),(4,2)\}$ .
