Ans: suppose (L, ≤) be a poset. If each subset {x, y} consisting of any two elements of L, has a glb (Infimum) and a lub (Supremum), after that the poset (L, ≤) is known as a lattice. The poset in (i) is a lattice as for each pair of elements in it, there a glb and lub in the poset. Likewise poset in (ii) is as well a lattice. Poset of (iii) is as well a lattice.
