What are the characteristics of cockroaches?

• A. They have leathery bodies with flat, oval shapes and short antennae.
• B. They have leathery bodies with flat, oval shapes and long, whiplike antennae.
• C. They are rounded and lack antennae.
• D. They have a hard horn and no wings.

Answer: (B)

Cockroaches are recognizable by a flattened, oval body with a leathery exoskeleton, and they have long, whip-like antennae that sense their environment. That combination—leathery, flat, oval body plus long antennae—is what lets them squeeze into tight spaces and navigate around. The option that matches this description is the one describing a leathery body, flat oval shape, and long, whiplike antennae. The other choices misstate features: one mentions short antennae, another says they lack antennae, and another invokes a horn and no wings, which doesn’t fit roaches.
