why does it has to be "and factored in" not "and factoring"? Can you please state if there is any grammar rule for such a parallelism please?

Choice E is not parallel. If it is going to have "and", it would have to end with "and factored in" in order to be parallel with "contained", and in order for the tense to be coherent. This is also why choice C is correct by comparison. By using "after factoring in" it is clear that the "factoring in" happened in the past.
