  - Correct answer : A — Apply tool result clearing to discard the superseded raw output while keeping the turn's outcome in history A . Correct. Once a tool result deep in history is no longer needed verbatim, clearing that raw output is one of the lightest-touch and safest forms of compaction, freeing attention budget while preserving the decision or outcome that mattered. B . Incorrect. A higher reasoning effort spends more compute per response but does not remove the stale tokens still occupying context, so the underlying dilution remains. C . Incorrect. Re-running the tool call adds another large, mostly redundant listing to history, increasing token consumption rather than reducing it. D . Incorrect. An added instruction competes for attention just like any other token and does not actually remove the large stale listing from context, so the disproportionate consumption remains.
