I agree with schooly20. .....only angels I'd put out of the picture,those are semiagresive not to mention the size they'll be when adults, almost like discus in size......
But if you like those combinations I'd go with option B
Also I can see that you have 4 zebra danios and those are semi agresive and superactive I don't think it's good idea have those in the same tank with platies...if I'm wrong correct me......
This infection is realy deadly .......I had like 50 guppies and columnaris killed 25 of them and one of my favorite breeders was among the dead ones ..........here it's a photo of it when it was alive
A molly won't bear the stress of a cycleless tank ........if you'r so eager to put fishes in your tank I'd suggest to add two tetras black skirt ,they are realy hardy and they will help you to cycle your tank....... :shout:
It takes from 2 to 6 months to complete the cicle .

salt in the water creates an hostil enviroment for bacteria that causes illnes and decease.....and also guppies platys and mollies comes from areas where rives meet the acean.....for those who say that these fishes are ok in fresh water without salt ...... I'm asking you this.....how 'd you feel...
