D Correct answer
Explanation

A circle is a collection of infinite points, and at each point on the circumference, a unique tangent can be drawn.

AI explanation

A tangent to a circle is a straight line that touches the circumference at exactly one point. Since an infinite number of points lie on the circumference of any circle, an infinite number of straight lines can be drawn touching it at exactly one point. Therefore, a circle can have an infinite number of tangents.
