Final answer:
The correct answer is Option 4. In cold-formed steel framing, king, jack, and cripple studs must match the dimension and thickness of the adjacent trimmer studs to ensure proper structural support around openings like doors and windows.
Step-by-step explanation:
In cold-formed steel framing, king, jack, and cripple studs shall be of the same dimension and thickness as the adjacent trimmer studs. This ensures structural integrity and uniformity in the framing process. Trimmer studs, also known as trimmers, are supporting studs placed on either side of a door or window opening, beneath the header. They help transfer load from the header to the floor system. The king stud is a continuous stud that runs from the top to the bottom plate, alongside the entire height of the wall, and the jack and cripple studs are shorter studs that support the header and the sill of an opening, respectively.
