If `A={a, b, c, d}`, then a relation `R ={(a, b),(b,a),(a,a)}` on A is

If Set A= {a, b, c, d} , then a relation R= {(a, b), (b, a), (a, a)} on A is :

If A={a,b,c} , then the relation R={(a,b),(b,a)} is:

If A = {a, b, c, d} then a relation R = {(a, a), (b, b), (c, c), (d, d)} on A is :

Given a set A = {a, b, c, d}, then the relation: R={(a,a),(b,b),(c,c),(d,d)} is reflexive?.

If A={a,b,c}, then the relation R={(b,c)} on A is

9.If A=[a,b,c] .then the relation R={(a,b),(b,a)} is : (A) Reflexive (B) Symmetric (C) Transitive. (D) None of these

If A={a,b,c} then the relation R={(a,b),(b,a)} is: (a)Reflexive (b) Symmetric (c) Transitive (d) None of these

Let R be a relation on A = {a, b, c} such that R = {(a, a), (b, b), (c, c)}, then R is
