**Educational Exercise: Understanding Rotational Angles**

**Problem Statement:**

1. *The wheel below is rotated counterclockwise about the center, point C.*

    [Diagram description: The diagram shows a circle divided into 10 equal sections, resembling a wheel with a central point labeled C. There are two marked points on the circle's circumference: A and B. The sections suggest equal spacing among these points.]

*Objective: Determine the rotation angle needed to move point A to point B.*

**Question:**
What is the angle of rotation that maps point A to point B?

**Multiple Choice Options:**
- A. 36°
- B. 72°
- C. 288°
- D. 324°

**Instructions:**

- Write down all key words and calculations as you determine the correct angle of rotation.
- Consider the number of equal sections in the wheel to calculate the angle between two adjacent points.


**Answer Choices (Circle the correct letter):**
- ○ A
- ○ B
- ○ C
- ○ D
