To copy the angle ∠BAC to point Q, the correct construction involves using a compass to measure the length between points B and C, and then creating an arc from point Q that corresponds to that angle.
Therefore, the correct response is:
Using a compass, measure the length from point B to point C. 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 ensures you replicate the angle accurately at point Q.
