Which of the following is a characteristic finding in chronic bronchitis?

The key idea here is recognizing the hallmark symptom of chronic bronchitis: a productive cough with sputum production. In chronic bronchitis, the airways are chronically inflamed and mucus glands and goblet cells enlarge, leading to copious mucus secretion. This mucous hypersecretion is what patients repeatedly cough up, and it often becomes purulent during infections. Clinically, this persistent, copious sputum production is the defining feature that sets chronic bronchitis apart from other COPD phenotypes or simple dyspnea. Intermittent mild to moderate dyspnea can occur, but it isn’t the defining finding and can be seen in many respiratory conditions. Hyperinflation on chest radiographs is more typical of emphysema, whereas chronic bronchitis may show bronchial wall thickening and increased markings rather than classic hyperinflation. Onset after a certain age isn’t specific enough to establish the diagnosis. So the presence of copious sputum production best identifies chronic bronchitis.
