Let R1 and R2 be two relation defined as follows : R1 = {(a, b) $$ \in $$ R2 : a2 + b2 $$ \in $$ Q} and R2 = {(a, b) $$ \in $$ R2 : a2 + b2 $$ \notin $$ Q}, where Q is the set of all rational numbers. Then :
- A.Neither R1 nor R2 is transitive.
- B.R2 is transitive but R1 is not transitive.
- C.R1 and R2 are both transitive.
- D.R1 is transitive but R2 is not transitive.
