Explanation:

The verb 'भरना' (to fill) can be used both transitively and intransitively. In the sentence 'बूंद-बूँद से घड़ा भरता है', the pot is filling by itself, meaning the action of filling is not being done *to* a direct object by an external agent. The subject 'घड़ा' is undergoing the action. Therefore, 'भरता है' is used intransitively here. If it were 'वह घड़ा भरता है' (He fills the pot), it would be transitive. Options A (Transitive) and C (Ditransitive) require a direct object. Option D (Compound) refers to a verb formed by combining two or more verbs.
