Which term describes bacteria that grow in pairs and are associated with infections such as pneumonia?

Explanation:
Bacteria that grow in pairs are described as diplococci. This term comes from cocci (spherical bacteria) that divide in one plane and remain attached, forming pairs. A classic example linked to pneumonia is Streptococcus pneumoniae, which is a diplococcus, so the term fits the description. Other shapes or arrangements don’t match this paired pattern: spirilla are spiral-shaped, bacilli are rod-shaped, and staphylococci form grape-like clusters rather than pairs.
