- A. postgres://$(DB_HOST):5432
- B. --db-host=$(DB_HOST)
- C. $(DB_HOST).svc.cluster.local
- D. $(DB_HOST)

**Answer:** postgres://$(DB_HOST):5432

**Explanation:** When a var is only part of a value, the converter uses the character next to it as a delimiter and records an index. A var in the middle of a string needs the same character on both sides, and here it has / before it and : after it. A var at the start, at the end or alone in the value converts fine.
