Ataper tap
Bbottoming tap
Cplug tap
Dfinishing tap
AI Explanation
The correct answer is A) taper tap. When internal threading for piping where the work permits the tap to be run entirely through, a taper tap should be used. Taper taps are designed with a gradual taper at the starting end, which allows the tap to easily enter and start the threading process. This taper also helps guide the tap through the full length of the hole, enabling you to begin and end the tapping smoothly. The other options are not appropriate in this scenario. Bottoming taps are used for threading blind holes, plug taps are for general-purpose threading, and finishing taps are used to clean up and refine the threads after initial tapping.
