Selected Answer: C
C. Self-built database supports quick deployment and elastic scaling. RDS offers quick deployment and elastic scaling: With RDS, you can provision and deploy database instances quickly, and you can also scale them up or down based on your requirements with ease. It provides automated management and scaling features. Self-built databases can be more challenging to deploy and scale: Building and managing your own database infrastructure requires more manual setup and maintenance, which can be time-consuming and may not offer the same level of scalability and ease of management as a fully managed service like RDS.
