Answer 2

Musn't we?

Explanation;

For writing question tags, the rule is that when the sentence is positive, you will use a negative question tag and when the sentence is negative, you will use a positive question tag.

Words that make a sentence negative - no, not, none, neither, seldom, hardly, scarcely, rarely, barely, nowhere, and never.

When the above negative words are found in a sentence, it makes it a negative sentence and a positive tag must be used.

Positive sentence --- Negative Question Tag

Negative sentence --- Positive Question Tag
