This question may seem open ended, but there’s one big deduction. The same division (either O or P) is inspected on Tuesday and Friday.
So, where can we put SS? Only Wednesday and Thursday have space.
Now the question was: where does P have to go? Tuesday and Friday can be either P or O.
But: who can go on Monday?
Not O, thanks to rule 2.
Not S, because S is inspected on Wednesday and Thursday.
P has to go Monday. A is CORRECT.
