IMO D
Given that one chair is taken, i think the remaining 4 dignitaries can be arranged 4!. That is 4*3*2*1=24.

If the president is sitting in the center, you only have 4 chairs left. There are 4 possibilities for 1st chair, 3 possibilities for 2nd chair, 2 possibilities for 3rd chair, and 1 for last chair. Multiply all those and you get 24. D.

We are given that we must arrange 5 people in a row; however, the president MUST BE seated in the center chair. Since the president’s seat is already determined, we need to arrange 4 people, which can be done in 4! = 24 ways.
