Correct answer: B (with a nuance).
TED limits talks to 18 minutes because that length is the “sweet spot” — short enough to hold an audience’s attention yet long enough to develop a meaningful idea. It’s a practical rule of craft rather than a hard scientific finding about attention spans, and it isn’t primarily about TV slots, cost, or simply fitting more speakers.
