Answer:
C). Impromptu Talk.
Step-by-step explanation:
An 'impromptu talk or speech' is characterized as any conversation that is produced on the spot without any prior planning, preparation, or rehearsal. Although Rhonda is working on that project, the sudden and unplanned update asked in a usual weekly meeting would be characterized as an 'impromptu talk.' This is because she had no idea regarding this and therefore, she didn't make any preparations for it and now she would have to produce it right on the spot with whatever knowledge she already has. Thus, option C is the correct answer.
