To make a copy of ∠BAC using the construction methods mentioned, the technically true response to choose would be:
Using a compass, measure the distance from point Q to point B. Then, make another arc by placing the pointed end of the compass on point Q and draw a small arc that intersects with the larger arc above point P.
This method is correct as it involves using the compass to replicate the arc, ensuring that the angles measure the same. The other choices do not align correctly with the geometric construction needed to copy the angle.
