A door can be utilized as a drywall control joint primarily when it goes vertical from the corners. This positioning allows the door to accommodate the natural movement that occurs in the building structure, particularly with temperature and humidity fluctuations. When drywall is installed, the seams are susceptible to cracking, especially at the corners where movement is most likely.

By aligning the door vertically with the corners, it effectively allows for this movement to occur without compromising the integrity of the surrounding drywall. This design technique provides a space that absorbs the expansion and contraction, which is essential in maintaining aesthetic and structural integrity in the wall assembly.

In contrast, the other options do not address the functionality of a control joint in the same way. A door that opens horizontally would not adequately serve the purpose of managing structural stresses related to drywall joints. Similarly, while solid core and lightweight materials may have their advantages in terms of soundproofing or weight, they do not contribute directly to the door's capability to function effectively as a control joint in drywall applications.
