Answer:
best completes this argument
Step-by-step explanation:
Circumference of circle =
Where d is the diameter of circle
We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to 
So, Number of sectors =
The arc length of each sector is the circumference divided by the number of sectors
Diameter d = 2r (r = radius)
Option b is true
Hence best completes this argument
