The best answer is:
C. increased access to an area
Humans generally create boundaries for reasons such as territoriality, protection and security, and safety. These boundaries help define ownership, control access, and provide a sense of security. However, the concept of creating boundaries for increased access to an area contradicts the purpose of establishing boundaries. Boundaries are typically meant to restrict access or demarcate a specific area, rather than facilitate increased access. Therefore, creating boundaries for the purpose of increasing access is not a common reason for establishing boundaries among humans.
