An instructor notices that the projector image is very dim, signaling that the bulb needs to be replaced. Learners seated in row two and beyond cannot distinguish the diagram being projected. No replacement bulb is available. In this situation, the MOST appropriate action for the instructor to take is to:
A.
continue without the projector, using other media for essential graphics
B.
postpone the class until a replacement bulb can be located
C.
continue using the projector and describe each slide to the class
D.
continue using the projector, but ask the learners to move closer to the projection
