This traffic sign warns of a sharp left bend ahead. The correct actions are to reduce speed before entering the bend and to keep as far to the right as safely possible to ensure better visibility and safety through the turn. You do not need to use your indicator, as this is not a turn or junction but simply a curve in the road. Your chosen answers are correct. When you see this sign in the future, always slow down and position your vehicle well to the right to safely navigate the curve.
