What procedure is used to square an exterior framed wall prior to being sheathed?

Use the 3-4-5 method to square wall.
Use the first sheet of sheathing to square wall.
Measure the diagonals to square wall.
Line bottom plate and first stud up with floor sheathing to square wall.

The correct answer is: Use the 3-4-5 method to square wall.

The 3-4-5 method is commonly used in construction to ensure the walls are square before sheathing is applied. This method involves measuring 3 feet along one wall, 4 feet along the adjacent wall, and then measuring the diagonal between these points. If the diagonal measures 5 feet, the wall is square. Options B, C, and D may not be as accurate or reliable as the 3-4-5 method and may result in an imperfectly squared wall.
