Adidn't we?
Bdid we ?
Cdidn't us?
Ddid they?
Answer:
A. didn't we?
Read Explanation:
Rule for Subject Pronoun: When the subject contains a phrase like "Some of us", "Most of us", "All of us", or "None of us", the pronoun in the question tag must be we (representing the speaker and others).
Rule for Verb / Tense: The main verb "wanted" is in the simple past tense (did + want). Therefore, the auxiliary verb for the tag is did.
Rule for Polarity: The main statement is affirmative (positive), so the question tag must be negative: didn't.
Combining these gives: didn't we?
