Verified step by step guidance1
Identify the nature of Wolbachia by recalling its classification: Wolbachia is a type of bacterium, not a virus or fungus.
Understand the ecological niche of Wolbachia: it is known to be an intracellular bacterium, meaning it lives inside the cells of its host organisms.
Recognize the typical hosts of Wolbachia: it commonly infects arthropods (such as insects) and some nematodes, rather than plants or free-living environments like soil.
Eliminate incorrect options by matching the characteristics: Wolbachia is not a virus, does not infect only plants, is not a fungus causing human disease, and is not free-living in soil.
Conclude that the true statement is the one describing Wolbachia as an intracellular bacterium infecting arthropods and some nematodes.
