I feel like we discussed how hydration helps with heat resistance too, but I can't recall if that's the main focus here. A) resist heat might be a contender.

I remember something about hydration making concrete workable, so B) become formable sounds familiar, but I could be mixing it up with something else.

I think hydration is related to how concrete gains strength, so I might lean towards D) develop green strength, but I'm not entirely sure.
