As interim relief, the Hearing Officer can:

Interim relief is a temporary measure designed to preserve the situation or prevent further harm until a final decision is made. The core purpose of interim relief is to restore the status quo ante, meaning to revert to the state of affairs that existed before the dispute or action arose. This ensures fairness and prevents one party from gaining an irreversible advantage during the proceedings.

• Option A (Grant final relief) is incorrect because interim relief is by definition temporary, not final.
• Option B (Suspend an EPO) might be a specific action, but restoring the status quo ante is the broader principle of interim relief.
• Option D (Award monetary compensation) is typically a form of final damages or settlement, not usually granted as temporary interim relief.

Therefore, restoring the status quo ante is the most accurate description of a Hearing Officer's interim relief power.
