The correct answer is option c) Statements 1, 2, and 3 are correct. The first step in the process of applying fiberglass to MDF wood when building speakers is to prepare the surface by removing any previous finish or paint residue. This ensures that the fiberglass adheres properly to the wood. After preparing the surface, the fiberglass should be cut to the size of the area to be applied. This ensures that the fiberglass covers the desired area without any excess. Finally, a certain amount of polyester resin should be measured and mixed with accelerator and catalyst. This mixture is then applied to the fiberglass in thin layers using a brush. Remember to always follow safety precautions and manufacturer's instructions when working with fiberglass and resin.
