What is a disadvantage of using a multimedia presentation?

A: (It does not allow audience interaction.)

B: (It requires special hardware, such as a computer and speakers.)

C: (Viewers have no control over the sequence of the presentation.)

D: (It cannot reach a large audience.)

Let's look at all the options:

A: (It does not allow audience interaction.) ion

This is false. The speaker has a complete control over when to stop the presentation, so if the audience has some question, the speaker can stop the presentation

B: (It requires special hardware, such as a computer and speakers.)

This is the correct answer! Setting up the hardware and software often takes a long time and delays the start of the presentation

C: (Viewers have no control over the sequence of the presentation.)

This might be true, but viewers have no control over any presentation - only the presenter has! (the presenter can involve the viewers thought)

D: (It cannot reach a large audience.)

This is false - a multimedia presentation can typically reach a wider audience than a non-multimedia one!
