The correct measure of angle ECD is 108°, therefore the third option is correct.

Explanation:

In the given figure there is a circle. Three points D,E and F lie on the circle. Since point C is the centre of the circle, therefore the distance of points D, E and F from the centre C is equal, i.e., radius (r).

The complete central angle of the circle is 360 degree and the measure of whole circle is also 360 degree.

It is given that the measure of arc ED is 108 degree. Since the ECD is the central angle of arc ED, therefore the measure of ECD is also 108 degree.

Thus, the correct measure of ECD is defined in option third.
