Answer:
B. Minor arc
Step-by-step explanation:
The central angle that is subtended by arc XY is less than 180° and it is not up to a semicircle.
A semicircle is half of a circle of which its central angle measure exactly 180°
The central angle of which an arc is subtended measures more than 180°.
Therefore, arc XY, which has a central angle that subtends it measuring 155° can be said to be a minor arc.
