Correct answer: C
Concept: In a direction-sense question, a right turn rotates the walker's facing direction by 90° clockwise, following the cycle North → East → South → West → North. The distances walked do not affect the facing direction — only the turns do.
Rachita starts by walking towards the north, so her initial facing direction is North.
First right turn: the facing direction rotates 90° clockwise from North to East.
Second right turn: the facing direction rotates 90° clockwise from East to South.
Third right turn: the facing direction rotates 90° clockwise from South to West.
Cross-check: three consecutive right turns together make a 270° clockwise rotation, which is the same as a single 90° turn to the left from North — and turning left from North also lands on West. This confirms the result: Rachita is facing West at the end of her walk.
