Spot the Odd Cone

Understand the puzzle

The exact puzzle

An ice-cream machine builds a cone from the bottom up using a repeating rule: two scoops of one flavour, then one scoop of a different flavour, then repeat. Reading each cone from the bottom, which one does NOT follow the rule? A: Vanilla, Vanilla, Choc, Vanilla, Vanilla, Choc. B: Straw, Straw, Mint, Mint, Straw, Straw. C: Choc, Choc, Straw, Mint, Mint, Vanilla. D: Grape, Grape, Blue, Rasp, Rasp, Grape.

Why this matters

Check a rule everywhere, because 'looks right' is not 'is right'

Take your time reading. There's no rush at all. Use the picture on the side to help it make sense, then tell me what it's really asking.
