A company uses Amazon RDS for a product database. The company wants to ensure the database is highly available. Which feature of Amazon RDS will meet this requirement?
- A. Read replicas
- B. Blue/green deployment
- C. Multi-AZ deployment
- D. Reserved Instances
Answer: C

Reserved Instances are related to cost savings and reserved capacity, not high availability.
