Given Point(x , -2) is in fourth quadrant that means x is positive
and Point(-3,Y) is in second quadrant that means y is also positive

since x and y both positive Point(x,y) must be in first quadrant

Sign Conventions across quadrants:

1st quadrant : x +ve, y +ve
2nd quadrant : x -ve, y +ve
3rd quadrant : x -ve, y -ve
4th quadrant : x +ve, y -ve


Now as per the question - (x -2) is in 4th quadrant which means x is +ve & (-3, y) is in 2nd quadrant so y is +ve. So (x,y) will be in 1st quadrant.

Ans : A. I
