- Correct answer : A — Append `LIMIT 1` to the statement so only the single most recent commit, which is listed first, is returned A . Correct: `DESCRIBE HISTORY` returns commits in reverse chronological order, so appending `LIMIT 1` isolates just the most recent commit, which is the fastest way to check what last night's run did. B . Incorrect: filtering on `operation = 'DELETE'` with no limit returns every delete across the table's entire lifetime, which is far more output than needed for a quick check of just the latest run. C . Incorrect: sorting ascending by version and limiting to one row returns the oldest commit in the table's history, the opposite of the most recent commit the analyst needs to inspect. D . Incorrect: grouping by operation type collapses rows across the entire history into aggregated buckets, losing the per-commit timestamp and version detail needed to confirm what happened in last night's specific run.
