On the real numbers, R = {(a, b): a <= b} is
AReflexive and symmetric, not transitive
BSymmetric and transitive, not reflexive
CAn equivalence relation on the reals
DReflexive and transitive, not symmetric
Answer & Solution
Correct answer: D. Reflexive and transitive, not symmetric
a <= a always and a <= b <= c gives a <= c, but 1 <= 2 does not give 2 <= 1.
