All of the above reasons are correct. The development of a complex language helped Homo sapiens survive by allowing them to exchange information, which facilitated coordination and cooperation among individuals in hunting, gathering, and other activities. This improved their chances of finding food and other resources necessary for survival. The ability to communicate through language also encouraged them to expand their territories and explore new places, finding new sources of food and shelter. Additionally, language enabled early humans to pass on knowledge and skills to future generations, including the ability to make and use complex tools that further enhanced their survival capabilities.
