I vote, they are judged by a just God and receive eternal life via His Mercy. Here's why:
1:
Revelation 20:13 And the sea gave up the dead who were in it [this would include children], and Death and Hades gave up the dead who were in them, and each one was judged according to their deeds.
"And each one, According to their deeds!" At this judgment, the GWTJ, it's each one based on their own deeds, not all through Adam.
Note, I do believe in what's termed "original sin". I do think that it's through Adam's sin that all humans die (our first/physical death). Additionally, and however, explaining physical death has almost nothing to do with explaining eternal life.
2:
Luke 18:16 But Jesus called them to himself, saying, “Allow the children to come to me, and do not forbid them, for to such belongs the kingdom of God.
Doesn't this speak for itself?
3:
Luke 23:34 And Jesus said, “Father, forgive them, for they know not what they do.”
I take the OP question to be about very young children, who literally don't know what they are doing yet (they do not know right from wrong, yet) Therefore, doesn't this same just principle for forgiveness Jesus applies to the Roman soldiers for their deeds their (following orders) apply to small children (even unborn)? I say it does. Again, perfect justice is perfectly applied. I have no doubt those same soldiers had many other unforgiven sins to account for at the GWTJ. But evidently, following Pilate's orders will not be one of them.

I know of no other Scripture that would call for another review/modification of my reasons #'s 1-3.
But boy, I sure do hear answer #1 (A) 'preached' a lot. It will be interesting the Scriptures used by any voting for answer A. (Or for that matter , C D or E. The last pastor (A) I asked, stumbled to produce any and didn't know what to say about my reasons 1, 2, and 3.
