If we put a glance over the list of suggested readings prescribed by the FPSC in the syllabus of GK-III (P.A.), we find on number 7 that the book "THE CASE FOR PAKISTAN" is written by Rafiq Afzal. So, the answer should be (a) and not (d). But, the way the question is asked and the word "for" is replaced by the word "of", it gets doubtful and the answers seems to be (d).
