Suppose we have three sets of numerical attributes: H (health), S (strength), G (gold). let's define a relation R on the set H × S × G by (x, y, z) R (p, q, r) if and only if x ≥ p or y ≥ q or z ≥ r

Which properties does this relation have? Select one or more:
a. irreflexive
b. symmetric
c. reflexive
d. transitive
e. antisymmetric
