Question

1. Assertion: A relation R = {(1, 1), (1,2), (2, 2), (2, 3) (3,3)} defined on the set A={1, 2, 3} is reflexive
Reason: A relation R on the set A is said to be reflexive if (a, a) ER, A a E A​

Answer 1

Step-by-step explanation:

Correct option is

A

reflexive but not symmetric

It is reflexive because (a,a)∈R.

It is not symmetric.

(a,b)∈R

But (b,a)∈/R

(1,2)∈R   but (2,1)∈/R

(1,2)∈R and (2,3)∈R & (1,3)∈R

So, R is transitive. 

So, only Option A  satisfies.
