Best answer
The correct choice is (d) Spur point bits

Easy explanation: Spur point bits have a central point and two raised spurs that helps keep the bit drilling straight. The bit cuts Timber very fast when used in a power drill and leaves clean sided hole. They are ideal for drilling holes for the Dowels as the sides of the holes are clean and parallel.
