Could you pls explain this

This is not quite an Orientation problem, since the answer choices are only partial scenarios.
But it's similar enough to an Orientation that we'd start off the same way: take one rule at a time and see if any answers break it.

Rule 1: this gets rid of (B), since Thursday has consecutive floors.

Rule 2: this gets rid of (A), since 8 appears before 2.

Rule 3: seems okay at first blush.

Rule 4: seems okay.

Rule 5: this gets rid of (C), since 4 is appearing on Wed.

So we're left with (D) and (E). My guess is that 3 - 7 - 5 will still come into play, but maybe it'll force consecutive numbers. We should write out (D) or (E) and put down who's left:

(D) 2, 6 | 4, 8 | __ __ | __ __ ...... who's left? 3 - 7 - 5, 1

This won't work! We need to get 3 - 7 - 5 on Friday / Saturday.

So (E) must be the answer. If we wanted a could be true to satisfy us, we could finish (E) off:
3, 6 | 2, 7 | __ __ | __ __ ...... who's left? 5, 8, 1, 6

They would all be legal in any spot.
