Answer:
C
Explanation:
A major arc is an arc that is greater than 180 degrees.
A minor arc is an arc less than 180 degrees.
An acute angle is an angle less than 90 degrees.
A central angle is the angle created in the center of a circle with 2 sides being the radius.
Thus, we can see in the figure that we are talking about the angle so we can eliminate major arc and minor arc.
Now, we clearly see that the angle is greater than 90 degree so it cannot be acute angle.
The correct answer is central angle as it goes with the definition.
