Correct answer: D. Sarcina
- A. Diplococci
- B. Octococci
- C. Tetrad
- D. Sarcina
Explanation
A group of eight cocci arranged as a cubical packet is called a sarcina, produced by division in three planes. Tetrad refers to four cocci, while diplococci refers to pairs, so choosing either confuses the number of cells in the arrangement.
