The correct answer is: 3) Biological siblings raised in the same house.
Explanation:
Personality, psychological disorders, and intelligence are three things that depend on two main factors: genetics and environment.
Option 3 - biological siblings raised in the same house: they share the same parents (genetics) and were raised in the same house (environment). This is the correct option.
Option 1 - monozygotic twins with entirely different homes: they share the exact same DNA (genetics) but their lives are completely different (environment). The twin living the wealthy family has probably had better nutrition and learning opportunities than the twin raised in poverty.
Option 2 - adopted children from different biological families but raised by the same parents: they share the environment but their genetics are completely different.
Option 4 - biological siblings living in different states with different families: they share some genetics but their experiences differ because of their raising.
