Well, we can cross out option A so far because the column and row totals should equal 100
Option B isn't looking good either so we can cross that out. That leaves us with option C or D
I got D
I could be wrong, but you can try it out
I'm here sorry, so it would be D? Thanks Could you help me with one more?
Yeah, I got D and sure :)
ask away :)

What do you think? i'm thinking A
While A and B look like they can be correct, A lacks the column for row totals and B lacks the column totals
This would make the tables incomplete and therefore incorrect
So A and B are in-correct, that leaves C and D.
I'm not sure whether it's C or D.
My best guess would be to go to C, because the total percentage at the end is 100%
Thanks for the help, I agree with C :))
You're very welcome :)
