The relation ≤ is a partial order if it is ___________
A. reflexive, antisymmetric and transitive
B. reflexive, symmetric
C. asymmetric, transitive
D. irreflexive and transitive
Answer:A
The relation ≤ is a partial order if it is ___________
A. reflexive, antisymmetric and transitive B. reflexive, symmetric C. asymmetric, transitive D. irreflexive and transitive
Explanation: Let A is a set and ≤ is a relation on A, then ≤ is a partial order if it satisfies reflexive, antisymmetric, and transitive, i.e., for all x, y and z in P. That means, x ≤ x (reflexivity);
