A) Reflexive
B) Transitive
C) Not symmetric
D) A function
Correct Answer: C
Solution :
Given A = {1, 2, 3, 4} R = {(1, 3), (4, 2), (2, 4), (2, 3), (3, 1)} (2, 3) Î R but (3, 2) Ï R. Hence R is not symmetric. R is not reflexive as (1, 1) Ï R. R is not a function as (2, 4) Î R and (2, 3) Î R. R is not transitive as (1, 3) Î R and (3, 1) Î R but (1, 1) Ï R.
