Answer:

The correct answer is option B.  30°

Step-by-step explanation:

Points to remember

The central angle of an arc is double the value of arc subtended on the the other part of the circle

From the figure we can see a circle with center F.

It is given that, mAB = mBC = mCD, means that, central angles of all these three arcs are equal.

To find the m<AFB

Fro the figure we get,m<CED = 15°

Therefore central angle of arc CD = 30°

So m<AFB = 30°
