Explanation:

In English, to ask a question in the past simple tense, we often use the auxiliary verb "did" followed by the subject and the base form of the main verb. The sentence requires an interrogative format because it asks about the identity of the person who informed him. Therefore, "Did Eric call" correctly structures the inquiry, relating directly to whether Eric made the call to inform about the acceptance of the bid.

So the complete question becomes: "Who did Eric call to inform him that his bid for the apartment renovation had been accepted?"

In summary, the correct phrase to fill in the blank is "Did Eric call".
