Final answer:

The strongest independent predictor of mortality in older patients with community-acquired pneumonia is co-morbidity.

Step-by-step explanation:

The strongest independent predictor of mortality in older patients with community-acquired pneumonia is 'B - Co-morbidity.' Patients with multiple health issues, particularly those with preexisting lung conditions like Chronic Obstructive Pulmonary Disease (COPD), heart failure, or a compromised immune system, have a higher risk of severe outcomes when they acquire pneumonia. These conditions make it harder for the body to fight off the invasion of pathogens like Streptococcus pneumoniae, the most common bacterial cause of pneumonia, and various viruses, such as influenza and respiratory syncytial virus (RSV). Co-morbidity refers to the presence of other medical conditions or diseases alongside pneumonia. Older patients with multiple underlying health issues are at a higher risk of complications and mortality.
