We have been given a circle. We are asked to find the measure of arc MN.
We know that the measure of all arcs in a circle is equal to 360 degrees. SO we can set an equation as:

Upon substituting our given values, we will get:




Therefore, measure of arc MN is 66 degrees and option 'c' is the correct choice.
