The correct answer is D) Etch the wire with acid. The reason this is the correct answer is that etching the wire with acid helps to create a better bond between the wire rope and the poured metal socket. Etching the surface of the wire rope creates a rougher texture, which allows the molten metal to adhere more effectively when it is poured into the socket. This ensures a stronger and more secure connection between the wire rope and the socket. The other options are incorrect because they do not directly address the step of preparing the wire rope surface for the poured metal. Installing a wire seizing (A) and ensuring the fiber core is well lubricated (C) are important steps, but they do not contribute to the bonding between the wire and the socket. Pouring molten babbitt metal into the socket (B) is a necessary step, but it does not address the preparation of the wire rope surface.
