Consider the following animals :
1. Hedgehog
2. Marmot
3. Pangolin
To reduce the chance of being captured by predators, which of the above organisms rolls up/roll up and protects/protect its/their vulnerable parts?

The correct answer is (D) 1 and 3.

Explanation:

Hedgehogs have spines which are known as quills, and they know how to use them. When they feel threatened, their quills immediately go up in full force. To protect himself, a hedgehog coils his head and feet into his body and creates a ball. When threatened, a pangolin will curl up into a tight ball and defend itself with its sharp-scaled tails. When the yellow-bellied marmot sees a predator, it whistles to alert the others in the area, then hides under a nearby rock pile until the threat has passed. They do not roll up.
