please check it out; if wrong, let me know.
The reason why A is wrong:
if we use "rented out more videos than it sold", it means that the number of rented videos can be, say, 4001 or 100000. The latter case will inevitably weaken the argument because of [100000(rented)+4000(sold)], which shows the possibility but in the other case of 4001, it will not do so since the number equals 8001 < 10000(total decline) = 4001(rented)+4000(sold).
