Option cSouth-East

  • CSouth-East
  • 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=13590=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.
