Answer: la clase
Step-by-step explanation:
The vocabulary item that does not belong is "la clase." This is because the other three options, "al lado de," "detrás de," and "encima de," are all phrases used to describe location or position, while "la clase" refers to "the class" or "the classroom."
"Al lado de" - next to or beside
"Detrás de" - behind
"Encima de" - on top of or above
In contrast, "la clase" refers to a classroom or a class. It does not convey a specific location or position
