A Correct answer
Explanation

A tangent to a circle is a line that touches the circle at exactly one point. Since there are infinitely many points on the circumference of a circle, there are infinitely many tangents.

AI explanation

A circle is a continuous closed curve, and a tangent is a line that touches the curve at exactly one point. Since there are infinitely many points on the circumference of a circle, exactly one unique tangent can be drawn at each of these points. Therefore, the total number of possible tangents is infinite, making the answer infinity.
