A security engineer is creating an AWS Lambda function. The Lambda function needs to use a role that is named LambdaAuditRole to assume a role that is named AcmeAuditFactoryRole in a different AWS account. When the code is processed, the following error message appears: "An error occurred (AccessDenied) when calling the AssumeRole operation." Which combination of steps should the security engineer take to resolve this error? (Choose two.)

A. Ensure that LambdaAuditRole has the sts:AssumeRole permission for AcmeAuditFactoryRole.

B. Ensure that LambdaAuditRole has the AWSLambdaBasicExecutionRole managed policy attached.

C. Ensure that the trust policy for AcmeAuditFactoryRole allows the sts:AssumeRole action from LambdaAuditRole.

D. Ensure that the trust policy for LambdaAuditRole allows the sts:AssumeRole action from the lambda.amazonaws.com service.

E. Ensure that the sts:AssumeRole API call is being issued to the us-east-1 Region endpoint.
