Flea larvae were described with which combination?

• A. 1 true, 2 false
• B. 2 true, 1 false
• C. both true
• D. both false

Answer: (C)

Flea larvae are worm-like and legless immature fleas that live in the environment near where hosts spend time. They don’t have legs and they feed on organic debris, especially the dried blood and flea feces (flea dirt) left by adult fleas. If the two statements in the question describe these two accurate traits—being legless and feeding on flea dirt—both are true. That’s why the combination selecting both true best fits the larval description.
