Bunuel is this question supposed to be without figure or is it just missing by mistake???

Looks like like figure should have been attached.

You are right, figure was missing. Edited. Thank you for noticing.

I believe the answer is A.

With the inscribed angle theorem (?) we know that XWZ covers 186 degrees (2*93). Because XYZ covers the area opposite of XWZ, the measure is (360-186)/2 = 87.

B by itself does not give us this information since the angles overlap

Also this question feels like a 700 level. Either way it's a good one

In a cyclic Quadrilateral, sum of diagonally opposite angles = 180

Statement 1: XWZ=93
Then, XYZ= 180-93= 87
Sufficient

Statement 2: YXW= 106
This angle has no relation with XYZ hence
Not sufficient

Answer Option A
