A company decides to stop non-production Amazon EC2 instances during the EC2 instances. The company's IT manager must receive notification in near real time whenever an EC2 instance that has an environment type tag value of non-production is started during the night.
Which solution will meet this requirement with the MOST operational efficiency?

A. Configure an flaws Lambda function with an SMTP client library. Subscribe the Lambda function to the flaws Health Dashboard to receive notification whenever an EC2 instance is in the running state. Configure the Lambda function to use Amazon Pinpoint to send email notifications to the IT manager. Deploy a second Lambda function to throttle calls from the first Lambda function during the daytime.

B. Deploy an flaws Lambda function that queries the Amazon EC2 API to determine the state of each EC2 instance. Use the EC2 instance scheduler to configure the Lambda function to run every minute during the night and to send an email notification to the IT manager for each non-production EC2 instance that is in the running state.

C. Create an Amazon EventBridge rule that includes the EC2 Instance State-change Notification event type. Filter the event to capture only the running state. Create an flaws Lambda function as a target of the rule. Configure the Lambda function to check the current time and the EC2 instances’ tags to determine the environment type. Create an Amazon Simple Notification Service (Amazon SNS) topic as a target of the Lambda function for notifications. Subscribe the IT manager's email address to the SNS topic.

D. Store the EC2 instance metadata, including the environment type, in an Amazon DynamoDB table. Deploy a custom application to an EC2 instance. Configure the custom application to poll the DynamoDB data every minute during the night and to query the Amazon EC2 API to determine the state of each instance. Additionally, configure the custom application to send an email notification to the IT manager for each non-production EC2 instance that is in the running state.
