Answer: B

Reason: The "atan2()" method used in the given code returns the arctangent of the quotient of its arguments, as the numeric values between -PI and PI radians. The returned digit represents the counterclockwise angle in radians (instead of degrees) between the positive X-axis and the point (x,y).
