Consider the binary relation, A = {(a,b) | b = a 1 and a, b belong to {1, 2, 3}}. The reflexive transitive closure of A is?

{(a,b) | a > b and a, b belong to {1, 2, 3}}

{(a,b) | a >= b and a, b belong to {1, 2, 3}}

{(a,b) | a > b and a, b belong to {1, 2, 3}}

{(a,b) | a <= b and a, b belong to {1, 2, 3}}

{(a,b) | a = b and a, b belong to {1, 2, 3}}

Consider the binary relation, A = {(a,b) | b = a 1 and a, b belong t

1.	Consider the binary relation, A = {(a,b) \| b = a 1 and a, b belong to {1, 2, 3}}. The reflexive transitive closure of A is?
