Which arrangement describes bacteria that occur in pairs?

Explanation:
Bacterial arrangement after division is described by prefixes that show how cells stay together. Occurring in pairs is described by diplo-, meaning two. When two cells remain attached after division, you get diplococci if the cells are spherical or diplobacilli if they’re rod-shaped. The word cocci refers to the shape (spherical), not the pairing, while strepto indicates chains and staphylo describes grape‑like clusters. So the paired arrangement is described by diplo-.
