Explanation:

✅ A. Care Provider Facility Specialty (or "Healthcare Practitioner Facility Specialty" in some orgs)
Purpose: Links specialties to specific practice locations (e.g., Dr. Smith performs surgeries at Hospital A but not Hospital B).
Use Case: Filters providers by specialty and location.

✅ B. Healthcare Provider Specialty
Purpose: Tracks a provider's specialties (e.g., Cardiology, Pediatrics) and their associated:
Facilities (where they practice)
Certifications (board-approved specialties)
Use Case: Powers filters like "Find a Cardiologist."

✅ D. Healthcare Provider Taxonomy
Purpose: Stores hierarchical specialty classifications (e.g., "Cardiology → Interventional Cardiology") using:
NUCC Taxonomy codes (U.S. standard)
Sub-specialty relationships (parent-child mappings)
Use Case: Enables searches like "Find a Pediatric Oncologist."

Why Not the Others?

❌ C. Care Taxonomy – Not a standard Health Cloud object.
❌ E. Care Specialty – Generic term; not a specific object.
