Answer: RESULT_SCAN

The RESULT_SCAN table function is specifically designed to return the output of a previously executed command within the last 24 hours. This directly matches the question requirement. The community discussion shows 100% consensus on answer D, with multiple comments confirming that RESULT_SCAN accesses results of previous queries. FLATTEN (A) is for semi-structured data, QUERY_HISTORY (B) returns metadata about queries, and TASK_HISTORY (C) returns information about task executions - none of these return the actual output/results of previous commands.
