Correct answer is A. From the log it shows that called party is transformed from 11112222 to 33334444.

I agree on the transformation but... why A and not B? There is no info about the calling party number (from header) so both A or B can be correct

i guess since the FROM in option B is 11112222 doesn't make sense, since you will not be calling yourself, so we assume the caller is 1000 instead of 11112222.
