Answer: Utilize S3Bucket and S3Key properties to reference the S3 bucket and key in the CloudFormation template.
The correct answer is D. To meet the requirements with the least development effort, the developer should use the S3Bucket and S3Key properties in the CloudFormation template. This approach directly references the S3 bucket and key where the Lambda function's deployment package is stored. This method is more straightforward and avoids the complexities of inlining code or specifying S3 keys in the ZipFile property.
