" 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}, then the relation R={(b,c)} 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, d} then a relation R = {(a, a), (b, b), (c, c), (d, d)} 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

State whether the statement is true or false ? If A= {a,b,c,d} and R={(a,c),(b,d),(b,c),(c,a),(d,b)} then R is a symmertric relation on A .
