Answer: Option 2 — Orangutan

Orangutans are highly intelligent great apes known for their remarkable tool-use capabilities. They have been extensively observed using sticks to scrape and extract insects from holes in trees and logs, probe for honey, and even fashion leaves into gloves or napkins. This behavior demonstrates their advanced cognitive abilities and problem-solving skills, making them one of the most tool-proficient non-human primates.

📝 Short Notes: Tool Use in Animals

• Orangutans: Use sticks to extract insects, honey, and seeds; use leaves as umbrellas, gloves, and napkins; found in Borneo and Sumatra.
• Chimpanzees: Use sticks to fish for termites, stones to crack nuts, and leaves as sponges for drinking water.
• Crows: Craft hooked tools from twigs to extract insects; demonstrate advanced problem-solving abilities.
• Sea Otters: Use rocks as anvils to crack open shellfish while floating on their backs.
• Elephants: Use branches to swat flies, scratch themselves, and modify sticks to reach food.
• Dolphins: Use marine sponges to protect their rostrums while foraging on the seabed.
