Let's break the movement down:
- First, Deepa moves 75 meters towards the North.
- Then, she turns left and moves 80 meters. Since she was facing North, turning left makes her face West. So, she moves 80 meters towards the West.
- Finally, she turns right at a 45° angle. Since she was facing West, turning right means she will now face South-West (because the right turn from West at a 45° angle brings her diagonally to South-West).
Thus, the direction in which she is finally moving is South-West, corresponding to option (d).
