If Demi performs:
Paulina must perform (from the condition that Paulina must perform if Demi performs).
Demi must perform (by definition).
Therefore, the minimum number of performers is 2: Demi and Paulina.
If Zozibini performs:
Demi must perform (from the condition that Demi must perform if Zozibini performs).
Zozibini must perform (by definition).
Therefore, the minimum number of performers is 2: Demi and Zozibini.
So, based on the conditions given:
The minimum number of contestants who must perform if Demi performs is 2.
The minimum number of contestants who must perform if Zozibini performs is 2.
Paulina must perform (from the condition that Paulina must perform if Demi performs).
Demi must perform (by definition).
Therefore, the minimum number of performers is 2: Demi and Paulina.
If Zozibini performs:
Demi must perform (from the condition that Demi must perform if Zozibini performs).
Zozibini must perform (by definition).
Therefore, the minimum number of performers is 2: Demi and Zozibini.
So, based on the conditions given:
The minimum number of contestants who must perform if Demi performs is 2.
The minimum number of contestants who must perform if Zozibini performs is 2.

To answer this question you can make a simple list to demonstrate who else must perform if a contestant performs.
If it is...
Andrea -> no one
Christiane -> Andrea
Paulina -> Andrea
Demi -> Paulina -> Andrea
Iris -> Demi -> Paulina -> Andrea
Zozibini -> Demi -> Paulina -> Andrea
So here we have the six outcomes for each contestant if they were to perform.
The question asks for the minimum number of contestants who must perform in the special two-hour episode, if the episode includes Demi's performance or Zozibini's performance.
If we look at the list we can see that if Demi performs, so must Paulina and Andrea. And if Zozibini performs, so will Demi, Paulina and Andrea.
Since the question asks for the number of contestants who will perform in the episode as a whole, and not the number of contestants who must perform after either Demi or Zozibini perform, I have understood the wording of the question to mean that Demi and Zozibini must also be included in the total number of contestants.
We can then conclude that there must be 3 in the case of Demi and 4 in the case of Zozibini.
