In kartagener syndrome, respiratory epithelial cell cilla is defective, resulting unable to clear sputum and pathogen, predisposing respiratory infections and bronchiectasis.

Correct Answer Answer is B

The answers is B.
Some strains of Pseudomonas have CFTR inhibitory factor as a virulence factor so it presents as a clinical case of cystic fibrosis sometimes.
It is not A cos in Kartagener, there is reduced clearance of mucous not increased mucous production.

But how can we differentiate that whether its pseudomonas or kartegener syndrome...because in kartegener,because of bronchiectasis there can be copious sputum,infections..
