Answer:
Last Option
Step-by-step explanation:
We have 10 people and two seats. Then we must choose 2 people out of 10 to occupy the seats.
The seats are different so the order in which people feel is important.
This is a problem of permutations
For the first seat I must choose a person of between 10.
For the second seat I must choose a person from 9.
So, if we call m the number of ways in which you can assign the seats:
[tex]m = 10*9\\\\m = 90[/tex]
