Final answer:
The correct verb form to fill in the sentence is 'le aburren'.
Step-by-step explanation:
The correct verb form to fill in the sentence is le aburren.
In this sentence, the subject 'Pablo' is singular, so we use the singular form of the verb 'aburrir', which is 'aburre'. However, since the object of the sentence 'las películas de amor' is plural, we use the plural pronoun 'les'. Therefore, the correct sentence is 'A Pablo le aburren las películas de amor'.
