A developer notices that a Lambda function which opens a new database connection on every invocation has high latency. The function makes repeated calls to the same downstream database. Which change to the function code best improves performance by taking advantage of execution environment reuse?

A Initialize the database connection inside the function handler so it is created on each invocation
B Initialize SDK clients and database connections outside the function handler so subsequent invocations can reuse them
C Store the connection details in the /tmp directory as user data between invocations
D Increase the function's reserved concurrency to force reuse of connections
