The answer is A.
In order to correct the punctuation in the sentence, it is necessary to replace the colon after the transition "therefore" with a comma. Transitions connect the ideas between two sentences, they are also called conjunctive adverbs. A transition occurs in the second of two related sentences, and, in the case of this sentence, a comma should follow "therefore".
