Which equation correctly describes the relationship between the measure of the inscribed angle and the measure of the intercepted arc in the figure?

Responses

m∠ABC=12mAC
the measure of angle A B C equals 1 half the measure of arc AC

m∠ABC=2(mAC)
the measure of angle A B C equals 2 times the measure of arc A C

m∠ABC=360°−mAC

the measure of angle A B C equals 360 degrees minus the measure of arc A C,

m∠ABC=mAC
the measure of angle A B C equals the measure of arc A C
Circle with two chords. Point C at 11 o clock, point B at 6 o clock, and point A at 8 o clock are on the circle. Segments A B and B C share a common end point at point B.
