B. Human heredity
C. Human demography
D. Eugenics

Answer

**Step-by-Step Solution:**

1. **Understanding Hereditary Qualities**: Hereditary qualities are traits that are passed from parents to offspring through genes. Genes are segments of DNA that determine various characteristics in an organism.

2. **Role of Genes**: The hereditary information that is transmitted to the next generation is controlled by genes. These genes dictate the physical and sometimes behavioral traits of an individual.

3. **Definition of Eugenics**: The term that describes the improvement of the human race through hereditary qualities is called "eugenics." Eugenics is a practice aimed at enhancing the genetic quality of a human population.

4. **Selective Mating**: Eugenics involves selective mating, where individuals with specific desired hereditary traits are chosen to reproduce. This selective process aims to propagate those traits in future generations.

5. **Goals of Eugenics**: The primary goal of eugenics is to reduce human suffering by eliminating undesirable traits, diseases, and disabilities from the gene pool. This is often referred to as "breeding out" these negative characteristics.

6. **Conclusion**: Therefore, the improvement of the human race through hereditary qualities is termed eugenics.

**Final Answer**: Eugenics
