Which symbol in Figure G7-1 represents a tapped inductor?

In standard schematic diagrams, an inductor is represented by a series of loops or a coil (looking like a spring). A 'tapped' inductor has a physical connection made at some point along the coil's windings, not just at the ends. This allows a circuit to use only a portion of the total inductance. On the exam's schematic diagram (Figure G7-1), Symbol 7 depicts exactly this: a coiled wire with a third connection line pointing to its center. Other symbols represent different components, such as a standard two-terminal inductor (Symbol 6), a transformer, or a variable inductor.
