Cast iron proved to be a beneficial material for the manufacture of water pipes and was used as a replacement for the original elm pipelines utilized earlier. These water pipelines were composed of individually cast pipe sections, often termed sticks, joined together by a bell and spigot joint. Here one end of the pipe stick is flared, termed the bell or socket, to enable the opposite end of the next stick, the spigot end, to be inserted to create a joint. The gaps in these joints were sealed with oakum to prevents the water from leaking out. A molten-lead joint was then run around the socket to ensure that the oakum seal remained in place.

So, the Given answer is correct.
