which pronoun correctly completes the completes the sentence when the direct object is replaced by a direct object pronoun?

Did you call me?
Tu blank llamaste?

The correct direct object pronoun to complete the sentence would be "me."

To determine the correct pronoun, we need to consider the role of the noun "me" in the sentence. In this case, "me" is the object of the verb "call" and represents the person being called.
Since the sentence is in the past tense ("Did you call...?"), we need to use the past tense form of the pronoun, which is "me."
Therefore, the correct sentence is: "Tu me llamaste?"
