The intercommunicating channels that permit collateral ventilation between adjacent alveoli and primary lobules are the Canals of Lambert and the Pores of Kohn, which are both found in the lung parenchyma. Bronchial anastomoses are connections between the branches of the bronchial tree and are not involved in collateral ventilation. Terminal bronchioles are the smallest airways that conduct air to the respiratory bronchioles and are not involved in collateral ventilation either. Therefore, the best choice is option C, which includes the Canals of Lambert and the Pores of Kohn.
