Step 1: Concept
Direction components in a Cartesian coordinate system (East = $+x$, West = $-x$, North = $+y$, South = $-y$).
Step 2: Analysis
- Horizontal component is negative $\rightarrow$ West ($-x$).
- Vertical component is negative $\rightarrow$ South ($-y$).
Step 3: Identification
The force vector lies in the third quadrant ($x<0, y<0$).
Step 4: Conclusion
Hence, the force is acting between South and West.
Final Answer:(C)
