A Correct answer
Explanation

With bookkeeper C fixed and secretary F fixed, we need one more bookkeeper (A or B) and 2 more secretaries from {D, E, G, H}. Rule I says A and C cannot be together, so we must pick B. Rule II says C and E cannot be together, so E is excluded. From {D, G, H}, we need 2 secretaries, but Rule III says D and G cannot be together. So we must choose either {D, H} or {G, H}. This gives exactly 1 valid combination: BCFDH.
