Answer:
Clarification needed in the question, however read below for what I think the answer could be.
Explanation:
The word for "to dance" is bailar, so I would say the conjugation would be "Ella baila en la clase de danza", if the missing word is there. If it is two sentences and you're supposed to put the correct conjugation in the second sentence, the missing word in the sentence "salsa, hip-hop, ballet, y merengue en la clase de danza" would be "salsa, hip-hop, ballet, y merengue están en la clase de danza."
There are missing words without indication of options as to where to put the verb to conjugate, so apologies if this answer didn't actually answer anything.
