Answer: Deploy an Amazon RDS Proxy to manage database connections, directing queries through the proxy.
The correct answer is D. Amazon RDS Proxy is designed to sit between your applications and the database to pool and share database connections. This reduces the number of concurrent connections to the database, thus preventing the 'too many connections' error. This solution requires the least operational effort as RDS Proxy handles connection management automatically, making it suitable for applications like AWS Lambda functions that may create many database connections simultaneously.
