I am not too sure there is a clear answer to this question: in principle, you could hold a speech of 10 minutes on any topic, but the depth of the treatment of the topic would have to be adjusted.
I would choose answer <span>C. the history of modern interior design: describing a history of anything requires a lot of details, and those need time.
Specifically, I find that options A and B are very easily condensed for 10 minutes: they are in any case not good options.
D. depends on whether this is just a general introduction or a very detailed, practically oriented, tutorial. </span>

Explanation:
The present perfect tense is the tense we use to talk about events that happened in the past but have present consequences. There are two types of this tense:
- The present perfect simple - used to talk about completed actions that have an influence on the present. The emphasis is on the result of the action.
- The present perfect continuous - used to talk about activities that started in the past and may continue in the present. The emphasis is on the activity itself.
