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?

Answer: d)1 and 3

The hedgehog was named because of its peculiar foraging methods. These animals root through hedges and other undergrowth in search of the small creatures that compose the bulk of their diet—insects, worms, centipedes, snails, mice, frogs, and snakes. As a hedgehog picks its way through the hedges it emits piglike grunts—thus, the hedgehog.
Hedgehogs have a coat of stiff, sharp spines. If attacked they will curl into a prickly and unappetizing ball that deters most predators. They usually sleep in this position during the day and awaken to search for food at night.
Hedgehogs hibernate in cold climates. In deserts, they sleep through heat and drought in a similar process called aestivation. They remain active all year in more temperate locations.

Marmots are large ground squirrels in the genus Marmota, with 15 species living in Asia, Europe, and North America. These herbivores are active during the summer, when they can often be found in groups, but are not seen during the winter, when they hibernate underground.
Marmots are large rodents with characteristically short but robust legs, enlarged claws which are well adapted to digging, stout bodies, and large heads and incisors to quickly process a variety of vegetation.
While most species are various forms of earthen-hued brown, marmots vary in fur coloration based roughly on their surroundings.

Pangolins are sometimes mistaken as reptiles, but they are actually scaly-skinned mammals. When in danger, the pangolin can roll into a ball, exposing only the tough scales for protection.
They certainly are one of the most trafficked mammals in Asia and, increasingly, Africa. Pangolins are in high demand in countries like China and Vietnam.
- Their meat is considered a delicacy and pangolin scales are used in traditional medicine and folk remedies to treat a range of ailments from asthma to rheumatism and arthritis.
- There is also demand in the Americas for their skins used to make leather products like boots, bags, and belts.
All eight pangolin species are protected under national and international laws but that is not stopping the massive international illegal trade in pangolins, which has increased in recent years because of growing demand.
WWF, together with TRAFFIC, is working in Asia and Africa to protect pangolins and other species from wildlife crime.
