The most common reasons for an employee’s unwillingness to accept a transfer are that mortgage rates are high, housing in the new location costs more, and the difficulty of selling the old home.

(A) that mortgage rates are high, housing in the new location costs more, and the difficulty of selling the old home

(B) that mortgage rates are high, housing in the new location costs more, and that it is difficult to sell the old home

(C) high mortgage rates, the greater cost of housing in the new location, and that the old home is difficult to sell

(D) high mortgage rates, the greater cost of housing in the new location, and it is difficult to sell the old home（E）

(E) high mortgage rates, the greater cost of housing in the new location, and the difficulty of selling the old home

虽然最后还是选了E，但一直犹豫不决，因为隐约记得difficulty in doing sth.这个用法。C虽然语法上说得过去，但相对而言更难以接受
