Correct answer is D.
It is true that burn up charts can be converted to cumulative flow diagrams by the addition of WIP, and they trend in the opposite vertical direction from burn down charts. It is also true that burn up charts that also track total scope (rather than burn down charts) separate out the rate of progress from the scope fluctuations. So the option that is not true is “Burn down charts indicate whether rate of effort changes are due to changes in progress rates or scope.”
