Answer 2

The correct answer is:

I would have bought the house by next week.

Explanation:

There are some sentences which are tricky it looks commanding enough to be taken as active voice but the construction of that sentence might be having marker words like 'by' and the reader might take it as passive by mistake.

These kinds of sentences and their understanding gets easier with more reading and understanding the content of the text.

The more a person is well read and versed, it gets easier to catch these twisted sentences.

The above sentence is also of that kind.

It has the word by in the answer but when changed to active from the passive, it is being directly informed by the speaker (I). So it is in active voice.
