D Correct answer
Explanation

If two parallel lines are tangent to a circle, the distance between them is equal to the diameter of the circle. Since the radius is 4 cm, the diameter is 2 * 4 = 8 cm.

AI explanation

When two parallel lines are tangent to the same circle on opposite sides, the distance between them is equal to the length of the diameter of the circle. Since the given radius is 4 cm, the diameter is calculated as 2 multiplied by the radius. The distance between the two parallel tangent lines is therefore 8 cm.
