Answer:
Not sitting in your assigned seat in school is best classified as a mutually responsive orientation as the others are not sitting on their assigned seat/desk.
Step-by-step explanation:
Take for an example- if a student is not sitting on his/her assigned desk choose a different desk to sit, this means that the other student whose seat taken by first student was empty.
The second student was using that desk (assigned desk) and in response of that the first student decided to sit on his/her desk.
