Options

A. segment
B. quadrant
C. sector
D. area

Answer

To solve the question "The region enclosed by an arc and a chord of a circle is called .............. of the circle," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- An **arc** is a part of the circumference of a circle.
- A **chord** is a line segment whose endpoints lie on the circle.

2. **Visualize the Circle**:
- Draw a circle and label its center as O.
- Draw two radii from the center O to points A and B on the circumference, creating an arc AB.

3. **Identify the Chord**:
- Draw a straight line segment connecting points A and C on the circumference, where C is another point on the circle. This line segment AC is the chord.

4. **Determine the Enclosed Region**:
- The region enclosed by the arc AB and the chord AC is the area we are interested in.

5. **Name the Region**:
- The region enclosed by an arc and a chord of a circle is called a **segment** of the circle.

### Final Answer:
The region enclosed by an arc and a chord of a circle is called a **segment** of the circle.
