Answer:
(d)

Core Books/NCERT
Hedgehogs are small mammals with short limbs and a body low to the ground. Their most distinctive characteristic is the thousands of stiff, sharp spines — harder and sharper than those of a porcupine, that cover the animal’s back and sides. When attacked, they curl into a prickly and unappetizing ball that deters most predators. Hence, 1 is correct. A marmot is a rodent of medium size with brown fur on its head and back as well as yellow fur on its belly. This animal is a herbivore eating nuts, leaves, seeds, flowers, grass, and grains. Hence, 2 is not correct. Pangolins are the only mammals wholly-covered in scales and they use those scales to protect themselves from predators in the wild. If touched or grabbed, they roll up completely into a ball, while the sharp scales on the tail can be used to lash out. Hence, 3 is correct. Therefore, option (d) is the correct answer.
