Which reptile is mentioned as an example of using large forelimbs to dig burrows and aid climbing?

• A. Monitor lizard
• B. Komodo dragon
• C. Gila monster
• D. Iguana

Answer: (A)

Forelimb power and claw use show up in reptiles that need to both dig and climb. Monitor lizards have notably strong, stout forelimbs with sharp claws that are well suited for scraping soil to create burrows and for gripping rocks or branches when climbing. That combination—digging with the front legs and using them to climb—fits the description well and is a classic example often cited in discussions of limb adaptations. The other reptiles mentioned don’t align as clearly with both tasks in the same way: some are burrowers or climbers by trade, but the dual use of large forelimbs for both digging and climbing is most characteristic of monitor lizards here.
