Let R be the relation in the set {1, 2, 3} given by R={(1, 1), (2, 2), (3, 3), (1, 2), (2, 3)}. Choose the correct answer.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → R is reflexive but neither symmetric nor transitive
$(1, 1), (2, 2), (3, 3)∈R$ (Reflexive)
$(1,2)∈R$ but $(2,1)∉R$ (Not symmetric)
$(1,2)∈R, (2,3)∈R$ but $(1,3)∉R$ (Not transitive)
