Answer:
B.the history of modern interior design
Step-by-step explanation:
When you are giving a 10 minute speech you have to keep in mind that you have very little time to present the topic, inform the audience and persuade them, in this case, 10 minutes is not enough to present the history of modern interior design, since modern interior design can be tracked down to 50 years ago, and you´d have to cover authors, designers, lines, colors, the uprising of the movement and many other topics in order to make a valuable speech, so 10 minutes are not enough.
