A new rule – there are two yellows on the bottom!
Start with your main diagram, and make sure the new rule doesn’t change anything:
It doesn’t. 6 and 3 still have to be green, because they’re beside and across from a red and a yellow. 1 still has to be red, because it’s beside a green, and the yellow for the row has already been used.
So, we have to fit two yellow onto the bottom row. We can fit one yellow in either space 8 or 10, but we can’t put two there.
That means we also need to put a yellow in store 2.
D is CORRECT.
