Which set contains only roles attributed to hormones in the slides?

The slides explicitly list **growth, development, metabolism, and reproduction** as processes in which hormones are involved. The other options include functions or systems not presented as the stated hormone-role list. Hormonal regulation is relevant to reproductive physiology because reproduction is one of the identified roles.\n\n**Key takeaway:** Hormones participate in four broad processes named in the material: growth, development, metabolism, and reproduction.\n\n**Glossary:** **Metabolism**: The collection of chemical processes occurring in an organism; **reproduction**: Processes involved in producing offspring.
