Which of the following is a type of lice that infests humans?

The correct answer highlights the three specific types of lice known to infest humans: head lice, body lice, and crab lice. Head lice are commonly found in the hair and scalp, feeding on human blood and causing itching. Body lice typically reside in clothing and move onto the skin to feed, often associated with poor hygiene or crowded living conditions. Crab lice, also known as pubic lice, primarily infest the pubic area but can be found in other coarse body hair such as underarms or facial hair.

Other choices may include terms that either do not correspond to recognized types of lice that affect humans or combine terms inaccurately. For instance, while ear lice are sometimes mentioned informally, they are not a recognized category of lice infesting humans. Similarly, hook lice or toe lice are not valid classifications recognized in medical or pest control practices.
