[" 2.If "A={a,b,c}" ,then the "],[" relation "R={b,c)}" on "A" is "]

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

If A={a ,\ b ,\ c} , then the relation R={(b ,\ c)} on A is (a) reflexive only (b) symmetric only (c) transitive only (d) reflexive and transitive only

If 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: (a)Reflexive (b) Symmetric (c) Transitive (d) None of these

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 Set A= {a, b, c, d} , then a relation R= {(a, b), (b, a), (a, a)} 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?.
