Bear
Hedgehog
Deer
Frog

The answer is D. Frog.

A bear, hedgehog, and deer are all mammals. Mammals are warm-blooded animals that have hair or fur. They give birth to live young and nurse their babies with milk. Frogs, on the other hand, are amphibians. Amphibians are cold-blooded animals that have smooth, moist skin. They lay eggs in water and do not nurse their young.

Here is a more detailed explanation of each option:

  • A bear is a large, furry mammal that lives in forests. Bears are omnivores, which means they eat both plants and animals. Some common types of bears include the brown bear, the black bear, and the polar bear.
  • A hedgehog is a small, furry mammal that has spines on its back. Hedgehogs are insectivores, which means they eat insects. Hedgehogs roll into a ball when they feel threatened.
  • A deer is a large, hoofed mammal that lives in forests. Deer are herbivores, which means they eat plants. Some common types of deer include the white-tailed deer, the mule deer, and the elk.
  • A frog is a small, slimy amphibian that lives near water. Frogs are carnivores, which means they eat other animals. Frogs lay eggs in water and do not nurse their young.
