GCHQ Holiday Puzzle Part 2

This is the first of 6 multiple choice questions.

On this first one I'm thinking the answer is SHALLOT...

But I haven't answered it yet...you must answer ALL 6 correctly to move on to Part 3 of the Christmas Puzzle!

Any thoughts? The word "not" in the question is throwing me off.
