Answer: The correct answer is #3. Dogs and humans are more closely related than snakes and humans

Answer:

3 & 4

Explanation:

Vertebrates are animals with back bone or vertebral column. Snakes, dogs and humans are all vertebrates.

Humans and dogs are mammals so they are warm blooded, give birth to their offsprings and have hairs or furs on their skin.

Snakes are reptiles and they mostly lay eggs, they are cold blooded, that is, they cannot produce their own body heat and they have scales on their skin like fish.

With this, humans and dogs are closely related than humans and snakes or even dogs and snakes.
