For the Answer it is BC, although the "AWSLambdaBasicExecutionRole" is the permission to write logs to CloudWatch https://docs.aws.amazon.com/lambda/latest/dg/lambda-intro-execution-role.html

Correct B & C A) Eliminated - A cross-account role is only required if the Lambda function needs to access resources in a different AWS account. There is no mention of cross-account access in the problem. D & E ) Eliminated - As Lambda function is scheduled to run independently

permission to list S3 buckets,s3:ListAllMyBuckets and Lambda function that grants it permission to write to the DynamoDB table. You can create a custom policy that includes dynamodb:PutItem, dynamodb:UpdateItem.

BC is the correct answer: we can deduce that a cloudwatch event has been created in order to invoke the lambda function once at hour. Once the function is invocated, it needs the permission to list the objects from the bucket and it needs also to insert record on DynamoDB

According to the question, Lambda function only needs to write to the dynamodb table and dynamodb wont need to invoke the function(doesn't make sense). rather, the function needs access to the s3 list.
