Answer: (b) Orangutan.
Orangutans, specifically the Bornean orangutans (Pongo pygmaeus) and Sumatran orangutans (Pongo abelii), have been observed using tools to scrape insects from tree holes or logs of wood. They exhibit a remarkable level of intelligence and tool use in their natural habitats.
As for the reference source, since you mentioned a preference for NCERT books, unfortunately, I don't have direct access to the content of specific books. However, the information about orangutans using tools is well-documented and can be found in various reputable sources.
Here are some suggested authenticative reference sources that you can consult for further information:
"Primates: The Amazing World of Lemurs, Monkeys, and Apes" by Marc Gave.
This book provides a comprehensive overview of primates, including orangutans and their tool-using behavior. It is suitable for general readers and students.
"Orangutans: Geographic Variation in Behavioral Ecology and Conservation" edited by Serge A. Wich, S Suci Utami Atmoko, Tatang Mitra Setia, and Carel P. van Schaik.
This book delves into the behavior, ecology, and conservation of orangutans, including their tool use. It is a more specialized resource but provides in-depth information for those interested in the topic.
In addition to books, you can refer to the websites of government organizations and international organizations for further validation and information. Here are a couple of suggested websites:
The International Union for Conservation of Nature (IUCN):
Official Website: https://www.iucn.org/
The IUCN is a reputable organization that provides extensive information on wildlife species, including orangutans, their behavior, and conservation status.
The Smithsonian National Zoo and Conservation Biology Institute:
Official Website: https://nationalzoo.si.edu/
The website provides educational resources and information on various animal species, including orangutans and their behaviors.
