Both passages A and B are clear in their feelings that the Roma face issues due to the legal definitions of "minority," e.g. lines 20-27 and lines 37-43. There is no debate to the problems that the Roma face due to the legal definition of "minority" in either passage.
Thus, answer choice (A) is not correct because the "problematic" situation that people of Roma descent are in is very clear and not up for debate. The nomadic characteristic of the Roma place them at a legal disadvantage to qualify as a minority.
So, answer choice (C) is the correct answer because it clearly explains that the "problematic" situation results in difficulties for the Roma since it is harder for them to get the same rights as other minorities.
Hope that clears things up! Please let us know if you have any other questions.
