A printer guide contains the box 'Reseat the toner cartridge, then power-cycle the unit.' What would turn this material into a troubleshooting-tree node?

Select one answer.

• Drawing the box with a diamond shape instead of a rectangle, since the geometry of the drawing is what distinguishes a decision tree from a flowchart in every published standard.
• Adding more consecutive actions to the same box, because a node earns its place in a tree by bundling enough steps that the follower saves page-turns compared to a flowchart.
• Nothing — reseating and power-cycling are already decision nodes, since any action performed on a device during diagnosis automatically splits the space of possible faults.
• Rewriting it as a test with branching outcomes — 'after reseat and power-cycle: does the fault persist? yes/no' — because a node must hold a question whose answers eliminate suspects; the actions alone are steps with no discriminating power.
