Well, we can cross out option A so far because the column and row totals should equal 100
anonymous
  • anonymous
Option B isn't looking good either so we can cross that out. That leaves us with option C or D
anonymous
  • anonymous
option c?
anonymous
  • anonymous
I got D
anonymous
  • anonymous
I could be wrong, but you can try it out
anonymous
  • anonymous

anonymous
  • anonymous

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

You're very welcome :)
