The thief stole my cloak as I was asleep in the waiting room.
Which is the better option to change voice of the above given sentence from the below given two options :
A) My cloak was stolen as I was asleep in the waiting room.
B) As I was asleep in the waiting room, my cloak was stolen.
I had four options with me out of which I managed to rule out two options but I am confused between these two options, my book has A as answer but my question is why A why not B ? Is there any difference in meaning ? Why A is better ?
