Introductory Psychology CLEP Prep Practice Exam

The key factor for determining overall development is the environment. While genetics and resilience do play a role in individual development, research has shown that the environment has a larger impact on development. This includes factors such as education, access to resources, and social influences. Unconditional love, while important for psychological well-being, is not a factor that determines overall development. Therefore, B is the correct option as it reflects the impact of external factors on an individual's development.
