A Correct answer
Explanation

For a tangent to be constructed from a point P to a circle, the distance from the center to P must be greater than the radius of the circle. 5cm is the only option greater than 3.5cm.

AI explanation

A pair of tangents can only be drawn to a circle from an external point, meaning the point's distance from the center must be strictly greater than the radius. Since the radius is 3.5 cm, the point must be situated at a distance greater than 3.5 cm. Among the provided options, only 5 cm satisfies this condition.
