Which set of construction steps could be used to construct an isosceles triangle EFG given line segment EF?

A.) Label a point G on segment EF and construct a line perpendicular to EF through point G. Draw segments EG and FG.

B.) Construct the perpendicular bisector of segment EF. Mark any point G on the perpendicular bisector except where it intersects EF. Draw segments EG and FG.

C.) Construct the perpendicular bisector of segment EF. Mark the intersection of this line and EF and label it G. Draw segments EG and FG.

D.) Mark a third point G not on segment EF. Draw segments EG and FG.
