Detailed Solution & Explanation

Let Home be at the origin (0,0)\displaystyle (0,0).
Office is 4 km East     (4,0)\displaystyle \implies (4, 0) and Club is 4 km North     (0,4)\displaystyle \implies (0, 4).
The midway point between Office and Club is:
Midway Point=(4+02,0+42)=(2,2)\text{Midway Point} = \left(\frac{4+0}{2}, \frac{0+4}{2}\right) = (2, 2)
Starting from (2,2)\displaystyle (2, 2), R moves towards Home (0,0)\displaystyle (0, 0).
The vector from (2,2)\displaystyle (2, 2) to (0,0)\displaystyle (0, 0) is (2,2)\displaystyle (-2, -2), which points in the South-West direction.
Since he is facing South-West, his back is facing the exact opposite direction:
Back Direction=North-West\text{Back Direction} = \text{North-West}
Hence, **Option B** is the correct answer.
