Which API request would return the contents of a file named 'events.parquet' with the ID '123-abc-456'?

The correct choice for retrieving the contents of a file named 'events.parquet' with the ID '123-abc-456' utilizes a GET request with a query parameter specifying the path to the file. This option effectively instructs the API to return the data associated specifically with that file, ensuring that the request is targeted toward the desired resource.

In the context of APIs, a GET request is designed for retrieving data. By appending the query parameter ?path=events.parquet, the request explicitly defines which file's contents should be returned from within the resource identified by '123-abc-456'. This clarity in specifying the file name helps the server correctly process the request and fulfill it by providing the exact data expected.

Other choices do not align with the expected functionality for fetching the specified file. For instance, a simple GET request without the path may not clarify which specific file you want to access, and using POST or DELETE not only deviates from the standard operation for retrieving data but also implies creating or removing resources rather than simply accessing them. Thus, the option that includes the path is the most precise and appropriate method for obtaining the requested file.
