D. Parallel, in any order

Answer 1

When installing wood studs and joists, gypsum boards should be applied first to the ceiling and then to the walls to ensure proper support, alignment and to provide sound containment and fire resistance.

Step-by-step explanation:

When installing wood studs and joists, gypsum boards should be applied first to the ceiling and then to the walls. This practice helps to provide a solid support for the edges of the gypsum boards on the walls, which can be particularly important when the wall meets the ceiling. By installing the ceiling boards first, you decrease the likelihood of sagging or improperly aligned seams between the wall and ceiling gypsum boards. Furthermore, applying the gypsum boards to the ceiling first allows for better containment of sound between floors and adds an additional layer of fire resistance at the top of the room.
