A company has an AWS Lambda function and an Amazon S3 bucket.

The Lambda function already has an execution role, so the correct fix is toadd CloudWatch Logs permissions to that same role. AWS documentation lists the required permissions for a Lambda function to write logs: logs:CreateLogGroup, logs:CreateLogStream, and logs:PutLogEvents. A separate role for the S3 bucket would not help because Lambda uses its own execution role when it runs. An S3 bucket policy is unrelated to CloudWatch Logs logging. The logs:GetLogEvents permission is for reading logs, not writing them. Updating the existing execution role is the least-complex and correct solution.
