The appropriate verb form to fill in the blank is 'está' when talking about the location of a place in Spanish.
Step-by-step explanation:
The appropriate verb form to fill in the blank is está.
When talking about the location of a place, we use the verb estar in Spanish. In this case, we are referring to Acapulco, which is a place in Mexico, so we use the form está to indicate that Acapulco is located in Mexico. The correct sentence would be 'Acapulco está en México.'
Remember, estar is used to talk about temporary states or locations, while ser is used to talk about permanent characteristics or professions. In this case, we are talking about the location of Acapulco, which is a temporary state, so we use estar.
