Question

# With reference to a universal set, the inclusion of a subset in another, is relation, which is Reflexive only None of these Symmetric only Equivalence relation

Solution

## The correct option is B None of these Since A ⊆ A . ∴ Relation ' ⊆ ' is relfexive  Since A ⊆ B , B ⊆ C ⇒ A ⊆ C  ∴ Relation ' ⊆ ' is transitive.  But A ' ⊆ ' B , ⇒ B  ⊆ A . ∴ relation is not symmetric.
