A relation R is defined on ordered pairs of integers as follows: $$(x,y)R(u,v) \text{ if } x<u \text{ and } y>v$$ Then R is:

1. Neither a Partial Order nor an Equivalence Relation
2. A Partial Order but not a Total Order
3. A total Order
4. An Equivalence Relation

ans is (A).. because the relation is not reflexive.. which is a necessary condition for both partial order and equivalence realtion..!!

not reflexive in all cases
For a relation to be partial order or equivalence relation it must be reflexive.
i.e. (x,y) is some element of the set then (x,y)R(x,y), but this doesn't satisfy the given condition of x<x, y>y

Option A
