(A) it immoral to work for wages or to own property, leaving it to his wife and daughters to support
(B) that working for wages or owning property was immoral and left to his wife and daughters the supporting of
(C) that

(D) it to be immoral
to work for wages and owning property, and he left it to his wife and daughters to be the supports of
(E)
there was immorality in working for wages or owning property, and he left it to his wife and daughters to support
Based on the options, E is wrong because "believed there was immorality" is not idiomatically correct.
C and D have parallelism issues - present participle and infinitives need to be used respectively.
A and B are both correct idiomatically - it is fine to use use the placeholder pronoun "it" in this case.
A is better than B as "to support" is more concise than using the complex gerund "the supporting of".
