Which bacterial form are round-shaped and may appear singly or in groups?

• A. Diplococci
• B. Cocci
• C. Bacilli
• D. Staphylococci

Answer: (B)

Round-shaped bacteria are cocci. They can exist as single cells or come together in different groupings such as pairs, chains, or clusters. The term cocci covers all these round appearances, which is why it fits the description of being round and able to appear singly or in groups. The other terms describe more specific forms or shapes: diplococci are pairs of cocci, bacilli are rod-shaped, and staphylococci refer to cocci arranged in clusters. So cocci is the correct, general term for this description.
