Answer: By adding custom attributes as annotations in the segment document.
The correct answer is A. In AWS X-Ray, annotations are key-value pairs that are indexed and can be used with filter expressions to search and group trace data. By adding custom attributes as annotations in the segment document, developers can effectively use these attributes for filtering. This is supported by the AWS documentation and multiple user confirmations.
