Correct Answer - C.
Following are the required segment fields in a Segment document.
1)Name.
2)Id.
3)Trace_id.
4)Start_time.
5)End_time.
6)In_progress.
Following are the optional segment fields in a Segment Document.
1)Service.
2)User.
3)Origin.
4)Parent_id.
5)http.
6)aws.
7)error, throttle, fault, and cause.
8)annotations.
9)metadata.
10) subsegments.
Option A is incorrect as service is an optional field in a Segment.
Option B is incorrect as HTTP is an optional field in a Segment.
Option D is incorrect as the parent_id field is required in the Subsegment field & optional in the Segment field.

Sure, I'd be happy to provide a detailed explanation!
When an application is integrated with the AWS X-Ray SDK, it generates trace data in the form of segment documents. These documents record information about the various components and resources that the application interacts with, allowing developers and operators to gain insight into the application's performance and behavior.
Each segment document contains a variety of fields that provide information about the segment itself and its relationship to other segments in the trace. Of the four fields listed in the question, one is required for every segment document: the "service" field.
The "service" field is used to identify the name of the AWS resource or component that the segment represents. For example, if a segment represents a request to an Amazon S3 bucket, the "service" field would be set to "s3". This field is important because it allows X-Ray to group related segments together in the trace, making it easier to understand the flow of requests through the system.
The other fields listed in the question are also important, but they are not strictly required for every segment document. The "http" field, for example, is used to record information about HTTP requests and responses, such as status codes and headers. If a segment represents an HTTP request or response, the "http" field should be included, but it is not necessary for other types of segments.
The "start_time" field is used to record the start time of the segment, and the "parent_id" field is used to identify the ID of the parent segment in the trace. These fields are important for understanding the timing and relationships between segments, but they are not strictly required.
In summary, the "service" field is the only required field in a trace segment sent by an application. The other fields listed in the question are important for providing additional context and information, but they are not strictly required for every segment.
