Your answer would be, C 5/45 and 4/36. In simplified form they both equal 1/9, meaning they are a proportion.
Answer:

Step-by-step explanation:
The length of any arc is calculated using the following equation:
s = r*θ
Where s is the length of the arc, r is the radius of the circle and θ is the angle in radians.
So, if we have a Circle O and a centrally angle AOB that measures π/3 radians, the value of the length of arc AB is calculated as:

Where r is the radius of the circle O.
The answer is D and it's pretty simple to do:
