B)  family studies 
C)  survey studies

Twin Studies

Research that compares the similarity between monozygotic (identical) and dizygotic (fraternal) twins to understand the influence of genetics versus environment on human traits.

Adoption Studies

Research studies that compare adopted children to their biological and adoptive parents to understand the influence of genetics and environment on traits.

Genetics

The study of heredity and the variation of inherited characteristics.
