Question

cystic fibrosis is an inherited condition in which the normally slippery mucous becomes thick and sticky. because of this condition, children with cystic fibrosis are more at risk to develop: tuberculosis asthma bronchiectasis pneumothorax

Explanation:

Cystic fibrosis causes thick, sticky mucus which can block airways. This obstruction and chronic inflammation can lead to the permanent widening of airways known as bronchiectasis. Tuberculosis is an infectious disease caused by a specific bacterium not directly related to the mucus - change in cystic fibrosis. Asthma is an allergic and inflammatory disorder of the airways not primarily due to the mucus characteristics in cystic fibrosis. Pneumothorax is the presence of air in the pleural cavity, not a direct consequence of the mucus problem in cystic fibrosis.

Answer:

Bronchiectasis
