Correct Answer: Option D

Explanation

1. The question asks which of the listed animals use the defense mechanism of rolling up to protect their vulnerable parts from predators. 2. Hedgehog (1): Yes, hedgehogs are well-known for rolling themselves into a tight ball when threatened, presenting a surface covered in sharp spines to predators and protecting their soft underbelly and face. 3. Marmot (2): No, marmots are large ground squirrels. Their primary defense mechanisms involve vigilance, warning calls, and retreating quickly into their extensive burrow systems. They do not roll up for protection. 4. Pangolin (3): Yes, pangolins are covered in large, hard scales made of keratin. When threatened, they roll up into a tight ball, using their sharp-edged scales as armor to protect their softer undersides. Therefore, both the Hedgehog and the Pangolin exhibit this behavior.
