**Right Triangle Relationships: Finding the True Proportion**

In the accompanying diagram of right triangle \( ABC \), altitude \( BD \) is drawn to hypotenuse \( AC \).

(Here, the diagram would show a right triangle \( ABC \) where \( \angle ABC \) is the right angle, and line segment \( BD \) extends perpendicularly from point \( B \) to segment \( AC \), where \( D \) lies on \( AC \)).

**Problem:**
Which statement must always be true?

**Options:**
A. \( \frac{AD}{AB} = \frac{AB}{AC} \)

B. \( \frac{BD}{BC} = \frac{AB}{AD} \)

C. \( \frac{AB}{BC} = \frac{BD}{AC} \)

D. \( \frac{AD}{AB} = \frac{BC}{AC} \)

The correct answer is option C.

**Explanation:**
In the context of the right triangle and the altitude drawn to the hypotenuse, several relationships involving similar triangles and geometric mean properties can be used. Here, statement C, \( \frac{AB}{BC} = \frac{BD}{AC} \), is derived based on the properties of similar triangles and the relationships of segments in a right triangle with an altitude drawn to the hypotenuse.
