Explanation:

This is a direction sense problem that requires working backward from the final direction. 1. **Final Direction:** Seema is facing South when she reaches her office. 2. **Last Turn:** She turned Right just before reaching her office. If she faced South *after* a right turn, we need to determine what direction she was facing *before* that turn. A right turn from East leads to South. Therefore, she must have been facing East before her final right turn. 3. **Turns Before Last:** Before the final right turn, she turned Left twice. So, she was facing East *after* making two left turns. To find the direction she was facing *before* these two left turns (i.e., when she started from home), we need to reverse these turns. * Reversing a Left turn is equivalent to making a Right turn. * So, we need to apply two Right turns from the East direction. * **First reversed turn (Right from East):** If you are facing East and turn Right, you will face South. * **Second reversed turn (Right from South):** If you are facing South and turn Right, you will face West. \nTherefore, Seema was facing West when she started from her home. \nTo verify, let's trace the path forward: * Start: West * Turn Left (1st): South * Turn Left (2nd): East * Turn Right (before office): South\nThis matches the given final direction. \nLet's analyze why other options are incorrect: * **A. North:** If she started North, after two left turns (West, then South) and one right turn (West), she would face West, not South. * **B. East:** If she started East, after two left turns (North, then West) and one right turn (North), she would face North, not South. * **C. South:** If she started South, after two left turns (East, then North) and one right turn (East), she would face East, not South. \nHence, the only consistent starting direction is West.
