Nice question, thank you.
I got it wrong because I checked first 3, but failed to check the last checkbox, and it looks like the latter is the one which causes the majority of wrong answers. The ratio of right and wrong is about 50/50 but the first 3 options are selected by the majority. In my case I was just affected by the nasty cold (or flu), so for some reason I could not force myself to think straight and could not separate the fix out of policy conditions part into fix and out of policy conditions. The out somehow stuck to the fix and so I read the sentence as ...fix out of policy conditions, so could not figure out what does it mean. Once I read the answer, I could see that it actually reads fix out of policy conditions. This taught me a lesson not to try answering QoD while being sick.
