Which of the following is not a vertical mode?

Explanation:
Vertical modes control the aircraft’s height changes and vertical path. Altitude Select commands the autopilot to reach and hold a specified altitude, so it directly governs vertical motion. Glide Slope provides vertical guidance along the ILS descent, another clear vertical mode. A go-around initiates a climb to ensure obstacle clearance during a missed approach, using vertical guidance to reach a safe altitude. Nav, by contrast, handles lateral guidance—keeping you on a course or tracking a navigation aid—without directly shaping the vertical profile. Therefore, Nav is not a vertical mode.
