Our aim is to solve the problem asked by Bahramnezhad and Azar in "KB-operators on Banach lattices and their relationships with Dunford-Pettis and order weakly compact operators". We show that a continuous operator R from a Banach lattice N into a Banach space M is a b-weakly compact operator if and only if R is a KB-operator.
