“prefieres la clase de arte o matemáticas” and the choices are 1- prefieres la clase de arte
2- preferir la clase de matemáticas
3- prefiero la clase de matemáticas

please help

prefiero la clase de matemáticas

Explanation:

the question is asking if you prefer art or math class. The "yo" or "i" form of preferir is "prefiero" .the first option does not work because it is in the "tu" or "you" form. The second option also does not work because the verb is not conjugated,
