b.at least 12 inches above the window

Explanation
A vent terminal within 10 feet horizontally of a door, openable window, or air intake must extend at least 3 feet above that opening. At 8 feet away the plumber is inside the 10-foot zone, so the 3-foot rise applies to keep sewer gas from entering the building.
