Gram +ve cocci arranged in groups (clusters):
- A- Streptococci.
- B- Staphylococci.
The correct answer is: B. Staphylococci.
Here's why:
- Staphylococci:
are gram-positive cocci that typically arrange themselves in irregular clusters, resembling grapes under a microscope. This characteristic is where the name "staphylococcus" comes from, meaning "cluster of grapes."
- Streptococci:
are also gram-positive cocci, but they typically arrange themselves in chains of varying lengths. The name "streptococcus" means "twisted chain," reflecting their chain-like arrangement.
Therefore, based on the characteristic of being arranged in groups or clusters, Staphylococci is the most accurate answer for gram-positive cocci with this arrangement.
