The correct answer is A. It is difficult to understand the part of "seven years' transportation to America". It seems to me that you should use a passive structure so as to place the kind of sentences that English courts were allowed to give first, and after mention that the first Penal Transportation Act was the one which introduced this change. The other answers do not apply to this sentence, there are no puntuation and spelling mistakes, and there are no unnecessary words.
I need more information to answer this question so please comment your question and ill be glad to help.
