Final answer:
Bacillus anthracis is the spore-forming rod bacteria that is nonmotile and noncapsulate. Other bacteria mentioned, such as Streptococcus pneumoniae and Staphylococcus aureus, do not have these characteristics.
Step-by-step explanation:
The type of bacteria described as spore-forming rods that are nonmotile and noncapsulate is B. anthracis (Bacillus anthracis).
These endospores allow the bacteria to survive in harsh environmental conditions and can remain dormant until favorable conditions arise.
In contrast, bacteria like Streptococcus pneumoniae, Staphylococcus aureus, and Streptococcus pyogenes do not form endospores and have different characteristics.
