Which term refers to round-shaped bacteria that appear singly or in groups?

Explanation:
Round-shaped bacteria are called cocci. The term cocci refers to spherical bacteria, which can exist as single cells or come together in groups or clusters, and may also appear in certain arrangements like in pairs or chains depending on the species. This makes cocci the best fit for describing bacteria that are round and can be seen alone or in groups. Bacilli, in contrast, are rod-shaped; diplococci describe a specific pairing of cocci rather than general single or grouped forms; spirilla are spiral-shaped, not round.
