Red Seal Carpenter Practice Exam

The depth of the buck is dependent on the height of the garage foundation wall, as the buck needs to extend past the foundation wall in order to properly support and frame the window. Therefore, the options with the higher height change (B and D) are incorrect, as a smaller buck depth would not be able to accommodate such a large change in height. Additionally, option A is incorrect as it has a smaller buck depth compared to option C, which could potentially cause issues with window installation and overall stability.
