A point both of whose coordinates are negative will lie in.
III quadrant
Step 1 - I Quadrant
The first quadrant is in the upper right-hand corner of the plane. In this quadrant, both x and y-coordinates are positive
Example -
Step 2- II Quandrant
The second quadrant is in the upper left-hand corner of the plane. In this quadrant, the x-coordinate is negative and the y-coordinate is positive.
Example -
Step 3- III Quadrant
The third quadrant is in the lower left-hand corner of the plane. In this quadrant, both x and y-coordinates are negative.
Example -
Step 4- IV Quadrant
The fourth quadrant is on the lower right-hand corner of the plane. In this quadrant, the x-coordinate is positive and the y-coordinate is negative.
Example -
so, a point both of whose coordinates are negative will lie in the III quadrant
Hence, Option C is a correct answer
