Answer: (C)

Verified step by step guidance

1. Bipedalism refers to the ability to walk on two legs, which is a defining characteristic of hominids.
2. One of the primary advantages of bipedalism is energy efficiency in locomotion, allowing hominids to travel long distances without expending excessive energy.
3. Walking on two legs frees up the hands, enabling hominids to carry tools and other objects, which is crucial for survival and adaptation.
4. Bipedalism also provides a higher vantage point, which can be advantageous for spotting predators and food sources over long distances.
5. While bipedalism does not directly improve climbing ability, it does allow hominids to move efficiently across open landscapes, which was essential for migration and exploration.
