Final answer:
Your belief that humans have no inborn abilities and can be completely shaped by environmental factors fits best with the concept of 'nurture' in the nature vs. nurture debate in psychology.
Step-by-step explanation:
If you believe that humans possess no inborn abilities and that a child's parents can mold them into whatever they want them to be, this belief aligns with the nurture side of the nature vs. nurture debate. This debate in psychology is concerned with whether our personalities and traits are the product of our genetic makeup and biological factors (nature), or if they are shaped by our environment and experiences (nurture). As your viewpoint emphasizes the role of environment and parental influence in shaping a child's development, it would best be categorized as (b) Nurture.
