When laying a concrete block wall start at:

1. the base and work upwards

2. the bottom row and work sideways

3. the center and work outward

4. the corners and work toward the center

The correct answer is: the corners and work toward the center

When laying a concrete block wall, it is essential to start at the corners and work toward the center. This method helps ensure that the wall remains straight, level, and structurally sound. By starting at the corners and working toward the center, you can establish a consistent reference point for the rest of the wall and avoid potential alignment issues. This approach also allows for easier adjustments if necessary during the construction process. Starting from the corners and moving towards the center creates a more stable and balanced structure, making option D the correct choice.
