Explanation:
Query parameters are a defined set of parameters attached to the end of a url. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. To append query params to the end of a URL, a '?' Is added followed immediately by a query parameter.

- C. Response body: "Success - Begin* Default response status code: 200
- D. Response body: "Error" Default response status code: 200
Answer: D
Explanation:
Response body: "Error" Default response status code: 200.
-------------------------------------------------------------------------------------------------------------------------------------------------
1) Payload is successfully set to "Success - Started Flow"
2) When HTTP Request throws an error, execution halts
#[error.description] = "ABC"
#[error.errorType] = "XYZ"
3) The On Error Continue scope handles the error. When On Error Continue scope is invoked, all the processors in error block are executed and success response is sent back to the client with payload which is set in error flow. In this case payload is set to "Error" value in error block.
4) "Error" is returned to the requestor in the body of the HTTP request with HTTP Status Code: 200 as On error continue always sends success error code.
