A sublattice(say, S) of a lattice(say, L) is a convex sublattice of L if _________(a) x>=z, where x in S implies z in S, for every element x, y in L(b) x=y and y

Answer»

Correct option is (c) x<=y<=z, where x, y in S implies z in S, for every element x, y, z in L

The explanation is: A SUBLATTICE S of a LATTICE L is a convex sublattice of L, if x ≤ z ≤ y and x, y in S implies that z belongs to S, for all elements x, y, z in L.
