I'm voting for B as the correct answer to this question. However, looking at the complicated nature of the question and how it is worded, one will think it's a nonsense question and has no significance. This takes my mind to the fact that there will be 15 questions in the exam that won't be graded whether you answer them correctly or wrongly. So, I'm suspecting this question to be one of those questions that will have no value in the exam but will form part of the 180 questions. so let's don't overemphasize on determining the correct answer to this question when we are seeing it as not properly worded for better understanding. Without prejudice to the exam content, I still consider option B as the correct answer to this question.
