  • DEast

Detailed Solution & Explanation

Let the cardinal directions be represented on a circular compass where North is 90∘\displaystyle 90^\circ, East is 0∘\displaystyle 0^\circ (or 360∘\displaystyle 360^\circ), South is 270∘\displaystyle 270^\circ, and West is 180∘\displaystyle 180^\circ.
Let anticlockwise (ACW) turns be positive (+\displaystyle +) and clockwise (CW) turns be negative (−\displaystyle -).
The initial direction is North-West (NW), which corresponds to the angle:
θ0=135∘\theta_0 = 135^\circ

Now, apply the series of turns:
1. A turn of 90∘\displaystyle 90^\circ clockwise:
θ1=135∘−90∘=45∘(North-East, NE)\theta_1 = 135^\circ - 90^\circ = 45^\circ \quad (\text{North-East, NE})
2. A turn of 180∘\displaystyle 180^\circ anticlockwise:
θ2=45∘+180∘=225∘(South-West, SW)\theta_2 = 45^\circ + 180^\circ = 225^\circ \quad (\text{South-West, SW})
3. Another turn of 90∘\displaystyle 90^\circ in the same direction (anticlockwise):
θ3=225∘+90∘=315∘(South-East, SE)\theta_3 = 225^\circ + 90^\circ = 315^\circ \quad (\text{South-East, SE})

Alternatively, we can compute the net turn:
Net Turn=270∘ (ACW)−90∘ (CW)=180∘ (ACW)\text{Net Turn} = 270^\circ \text{ (ACW)} - 90^\circ \text{ (CW)} = 180^\circ \text{ (ACW)}
A turn of 180∘\displaystyle 180^\circ from North-West points directly to the opposite direction, which is South-East.
Hence, **Option C** is the correct answer.
