Which symbol in figure G7-1 represents a field effect transistor?

In schematic diagrams, a Field Effect Transistor (FET) is depicted with three distinct terminals: a gate, a drain, and a source. Symbol 1 represents a junction FET (JFET), characterized by a straight vertical line representing the channel, with the gate lead drawing an arrow that points either inward (N-channel) or outward (P-channel). Unlike bipolar junction transistors (like Symbol 2), which use slanted lines for the emitter and collector, the FET symbol clearly distinguishes its connections with perpendicular lines for the source and drain attached to the straight channel line.
