Let N denote the set of all natural numbers. Define two binary relations on N as R = {(x, y)

\in

N

\times

N : 2x + y = 10} and R2 = {(x, y)

\in

N

\times

N : x + 2y = 10}. Then :

A
Range of R1 is {2, 4, 8).
B
Range of R2 is {1, 2, 3, 4}.
C
Both R1 and R2 are symmetric relations.
D
Both R1 and R2 are transitive relations.
