Does D look like it's the correct answer?

Anya is constructing a circle inscribed in a triangle ABC. In the first step she constructs the angle bisectors of angle B and angle C and labels the point of intersection of the bisectors as Q. Which could be the next reasonable step?

She will construct a line passing through point Q and vertex A.

She will construct a line through vertex A perpendicular to segment BC.

She will construct a perpendicular bisector of segment BC.

She will construct a line through point Q perpendicular to segment AB.
