Solution
The correct option is D III and IV only
The coordinates of any point on 2D plane is given in form of (x,y) coordinates where x-coordinate is the coordinates along X-plane and similarly y-coordinate along Y plane
In order to be a point in 4th Quadrant, the value of x has to be positive and the value of Y should be negative.
Hence the points III and IV are in the 4th Quadrant.
