Which category of bacteria is commonly associated with pneumonia when appearing as pairs?

Explanation:
Diplococci are cocci seen in pairs, which is a classic arrangement for bacteria that cause pneumonia. The most well-known pneumonia-causing diplococcus is Streptococcus pneumoniae (the pneumococcus), a Gram-positive diplococcus, commonly linked to community-acquired pneumonia. Seeing bacteria in pairs points to the diplococci pattern, making this the best fit. In contrast, cocci describe spheres in general, bacilli are rod-shaped, and streptococci are cocci in chains, not paired, so they don’t align as specifically with pneumonia in the paired form.
