Which statement about fleas beetle hind legs is true?

• A. They are stout and used for jumping
• B. They are used for swimming
• C. They are absent in adults
• D. They are used for feeding

Answer: (A)

Jumping-ability provided by stout hind legs is what flea beetles rely on. Their hind legs feature enlarged hind femora and strong joints that act like springs, letting them launch themselves in a quick, powerful jump when disturbed. This adaptation helps them escape from predators and move between plants efficiently, which is exactly why the statement about their hind legs being stout and used for jumping is true. Hind legs aren’t there for swimming, they aren’t absent in adults, and they aren’t used for feeding—the legs aren’t mouthparts or feeding tools, they’re built for propulsion and evasive movement.
