What is the measure of angle YQZ in the figure?

(1) XQ bisects angle WQZ; YQ bisects angle XQZ.
(2) Angle WQX measures 50°.

I don't agree with OA.

I think ans should be

C is the answer.

Statement 1: We know that WQX = XQZ and XQY = YQZ. But we don't have any values to manipulate. Not Sufficient
Statement 2: Not enough information to determine angle YQZ. Not Sufficienc.

Combined: Since WQX = 50, WQZ = 100. Since YQZ is a bisector of XQZ, and we know that XQZ = 50, we know that YQZ has to be 25 degrees as a bisector cuts the larger angle into two equal smaller angle.s
