Which of the following is a species of lice?

• A. Bed Bug
• B. Tick
• C. Head Louse
• D. Mosquito

Answer: (C)

Lice are small parasitic insects that live on humans and feed on blood. Among the options, the head louse is a species of louse that commonly infests the human scalp (Pediculus humanus capitis). Bed bugs are not lice; they’re different true bugs. Ticks are arachnids, not insects, and mosquitoes are insects but belong to a different family, not lice. Because the head louse is the actual louse species listed, it’s the correct answer.
