Question Analysis

This question focuses on identifying the type of arc in a circle, testing the understanding of different arc classifications as well as the difference between arcs and angles.

Key Concept Explanation

Semi - circle Arc: An arc that is exactly half of the circle's circumference, measuring 180 degrees.

Central Angle: An angle with its vertex at the center of the circle, formed by two radii. It is not an arc.

Major Arc: An arc that is greater than a semi - circle, measuring more than 180 degrees. It is named using three points (the two endpoints and a point on the arc).

Minor Arc: An arc that is less than a semi - circle, measuring less than 180 degrees. It is named using its two endpoints.

Step-by-Step Solution

1. Observe arc : Arc  is clearly less than half of the circle's circumference.

2. Based on the definitions, since arc
