If $C = \{2, 5\}$ , $D = \{4, 6, 7\}$ , $x \in C$ , $y \in D$ , the relation $x + 1 < y$ gives—

a $\{(2, 4), (2, 6), (2, 7), (5, 6), (5, 7)\}$
b $\{(2, 4), (2, 6), (2, 7), (5, 7)\}$
c $\{(2, 6), (5, 7)\}$
d $\{(2, 4)\}$

ব্যাখ্যা

Checking $x+1<y$ for each pair: with $x=2$ (so $x+1=3$ ), all of $4,6,7$ are greater, giving $(2,4),(2,6),(2,7)$ ; with $x=5$ (so $x+1=6$ ), only $7>6$ , giving $(5,7)$ . Note $(5,6)$ fails since $6\not<6$ .
