I would go option E.

I have been an eve player since 04' and am just getting into the multi-boxing via software thing. Having the ability to get in and out of 0.0 space with a carrier alt is essential. Get the carrier & train the alts on the other account or 2 for cynos & you can make yourself one of the richest players in eve with the ability to get anywhere in the game if your alliance moves.

I would even go as far as to propose option F:

Get a 4th account which, once you have skills will be easy to keep going via PLEX so you don't have to pay cash for em. train a main on each for the tengu thing as you can come in and out of 0.0 at will with a travel fit on each. This will be your initial money making setup. Use this to run Sanctums, Havens & Forlorn Hubs. Once you are doing that you should train the characters to where you have at least 1 carrier with Jump Calibration 5 and all the alt slots on every account train for cyno alts. I have a nice lil skill set to use too:

All Racial frigs 3
Cyno Field Theory 3
Propulsion jamming 3
High Speed Maneuvering 1
Hull Upgrades 1

(Use the Tristan frigate as your cyno ship)

This gets you mobile where you can go anywhere in eve whenever you want, & when you have 8 cyno alts that you can use you can pretty much reach the furthest reaches of 0.0 while remaining 100% self sufficient. Next step is where you REALLY want to have every character cyno capable with that skill set.....

Start training another character for a jump freighter with all the lvl 5 skills, 3rd main for a noctis, and another for a dread.

This all eventually leads to you having 1-2 characters making insane iskies with a noctis alt following around salvaging everything behind you making you 100% profit with no waste and the JF to haul it all into empire for best refine / meltdowns & frigging epic weekly sales profit.

Use the isk to send that dread pilot to titan level & the first carrier to mothership level and train another standard carrier. That's pretty much the end of the game there.

Keep in mind that this will take years to accomplish, but with the insane isk coming in off of your initial multi-tengu setup you can pretty much always have +5 attribute implants in your head the whole time & save years in the long run by doing it that way. This is also what I do, only the startup part was much slower on my end as I had no multi-boxing software, or multi-tengu setup.
