I'd go for B. Here's my line of thought:

Even though they asked me to be remembered, and I care for them, after they're dead it doesn't matter to them if they are remembered or not. There is no harm in them not being remembered, because they are not there to be harmed.

Keep in mind that there is a non-zero cost to the un-remembered, in that they may be cognizant that they will not be remembered prior to their death.

I would tell the couples that I am going to choose A, but instead choose B.

Which makes you a bad with respect to most varieties of deontological and virtue ethics.

[IsaacSchlueter]

But deontology and virtue ethics are just shorthand heuristics for consequentialism, to deal with the fact that humans tend to be very bad at doing utilitarianism properly.

When the consequences are clear, and you have no other options, the rational choice is to ignore virtue ethics.

Of course, in real life, there is almost never such a clear-cut problem as this, and pat examples are often used by those who want to throw away virtue ethics out of convenience rather than actual utilitarian benefits.
