Option (D) is the correct one.
(-1 , 0) is the point that represents the point on the unit circle and corresponds to -π.
Given, a unit circle
and we have to mention the point on the unit circle that corresponds to -π.
As, the equation of a unit circle is
x² + y² = 1
now -π is represented by the left side of the x-axis
therefore to represent the given point we have to take a point on x-axis that will be at the left side of the origin and at the unit distance from the origin.
So, (-1 , 0) is the point that represents the point on the unit circle and corresponds to -π.
Hence, (-1 , 0) is the point that represents the point on the unit circle and corresponds to -π.
