Thanks for your correction @Trishul.

Yeah it is a bit ambiguous but from what I understand, 'none of these' means none of the above 4 'options' only follow. It doesn't say anything about any combination I, II and III which could have been complementary to each other.

Whereas option 'none follows' means none of the 3 'conclusions' follows individually hence, no combination of them would also follow.

Precisely. Unless you are trying to give the student the option of saying that more than one conclusion is correct. In which case, you should actually say that, rather than give a completely ambiguous option as an answer and then mark it wrong.
