* The most common reasons for an employee’s unwillingness

[Siddzy]

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

I understand y E is right , but even option B is parallel. If so wat is the error in B

[san]

In B - and that it is difficult to sell the old home

That is not required.

[SAN]

In B - 'it ' is invalid referent

[VP]

My friend E seems better than B because it uses parallel noun phrases, while in B the verb phrases used are not exactly parallel and use the "it" which has no antecedent.
