It is B.
A threading tool should IDEALLY have positive rake because it will give good chip flow control. Better chip flow results in better quality threads with less burrs and scratches.

If we use positive rake angle then the chip flowing sideward direction will induce a thrust force on threads and produce crack and thread become weak.

@Rahul.
In carbide tool, the negative rake angle will be used.

What type of rake in carbide tools?

A single point thread cutting tool should have zero rake angle because what actually happens with the positive rake angle is that the chips formed under the rake face may flow side ward and try to weaken the thread formed.
Hence it is advisable to use zero rake angle for thread cutting and also for brass work pieces.
