Choose your poison, however, living long enough to fight for a chance to change, defeat or restructure that poison, in whatever form it comes, is what I choose. Choice B) does not give you that option unless it's your understanding that:

It is good to have someone living as long as possible who actually wants to make the world a better place.
But, we all know who will be the ones actually benefiting from this.
The ones who don't give a rats ass about anything, only selfishly living longer just to make more money, have more power. Hoarders who are rather a disease for humanity then being useful.
In an ideal world it would be a fantastic thing. But we aren't living in one. We can try, but unless 90% of humanity stops acting like a maniac, it will divide humanity on another level.
We can't cope with the fact properly, if our neighbour has a bigger car then ours. Imagine how people would cope with the fact, that some of us can live for hundreds of years.
Immortality is a nice thing, but not until the minds are cleared, poverty, hunger, closed mindedness, are banished and humanity as a whole can act and decide without having constant internal struggles.
Just look at the idiots who are against vaccinations, religious nut-jobs, greedy, selfish, maniac, egocentric, etc...
All the beautiful traits of humanity. Do you want to give those power to live long, or maybe forever?
Would you prevent new generation to blossom and create something new, by selfishly clinging to life and not letting go to give way for the change? It is a common thing that the older you are, the less you can change, or keep up with trends. And this is not only about are ageing bodies. We might have the risk to stop evolving. To stop innovating, exploring, etc...
I advise to you to read "2br02b" from Kurt Vonnegut. A short story about our society perfecting immortality. It is very interesting.
And to answer your question. I would probably choose 'A', even if I fear that it will have a very negative impact on humanity.
Choose your poison, however, living long enough to fight for a chance to change, defeat or restructure that poison, in whatever form it comes, is what I choose. Choice B) does not give you that option unless it's your understanding that:
C) There is another option
D) Choice A) will someday positively impact the reanimation of those who've selected Choice B).
Choose wisely.
