Question:
If
$X = {x_1, x_2, x_3}$
and
$Y = {x_1, x_2, x_3, x_4, x_5}$
then find which is a reflexive relation of the following ?

$R_1 : {(x_1, x_1), (x_2, x_2)}$
$R_1 : {(x_1, x_1), (x_2, x_2), (x_3, x_3)}$
$R_3 : {(x_1, x_1), (x_2, x_2), (x_1, x_3),(x_2, x_4)}$
$R_3 : {(x_1, x_1), (x_2, x_2),(x_3, x_3),(x_4, x_4)}$

The Correct Option is
B
Solution and Explanation
(a) Non-reflexive because
$\left(x_{3}, x_{3}\right)\notin R_{1}$
(b) Reflexive (c) Non-Reflexive (d) Non-reflexive because
$x_{4}\notin X$
