Help the accused roommate recount the morning's interrogation to a friend. Choose the grammatically correct sentence.

The correct answer is She asked me where I had hidden her favorite mug.

When reporting a Wh- question (who, what, where, when, why, how), we keep the question word but change the word order to a standard statement (Subject + Verb). We also drop auxiliary verbs like do/does/did and shift the tense backward (from simple past "did you hide" to past perfect "had hidden").
