Which letter corresponds to Vertical trunk?

• A. Compartment L
• B. Compartment M
• C. Compartment T
• D. Compartment Q

Answer: (C)

The key idea is matching orientation to labeling. The vertical trunk is the line that runs straight up and down in the diagram. In this layout, the label assigned to that vertical line is Compartment T. The other compartments correspond to trunks that run in different directions, so they don’t match the vertical trunk. A quick way to confirm is to trace the vertical line from top to bottom and see which compartment label sits on that line—it's Compartment T.
