Let A={1,2,3,4} and R be a relation in A is given by R={(1,1)(2,2)(3,3)(4,4)(1,2)(2,1)(3,1)(1,3)},Then R is

This question has multiple correct options

Answer

Correct option is

A

reflexive

B

symmetric

The above set contains,

(1,2)→(2,1)

(1,3)→(3,1)

And (1,1)(2,2)(3,3)(4,4)

(2,1) and (1,3) is present but not (2,3) hence not transitive

Hence, the given relation is reflexive and symmetric.
