Ans) d 

Exp) Option d is correct. 

Option 1 is correct.  Hedgehogs are small nocturnal spiny mammals. When they are frightened, or annoyed, hedgehogs will roll into a ball so that a predator will feel the full brunt of its sharp spines and will then leave the hedgehog alone.

Option 2 is incorrect. Marmotsare relatively largeground squirrels with 15 species living in Asia, Europe, and North America.  They are the heaviest members of thesquirrelfamily. It does not roll up to protect itself. 

Option 3 is correct. Pangolins are actually mammals. They are the only mammals wholly-covered in scales and they use those scales to protect themselves frompredators in the wild. Under threat, a pangolin will immediatelycurl into a tight ball and will use theirsharp-scaled tails to defendthemselves.
