If you choose the third mode, you choose how the counters will be distributed as you cast the spell. Notably, if you choose to put one +1/+1 counter on each of two target creatures, and one of those creatures becomes an illegal target in response, the +1/+1 counter that would have been put on that creature is lost. It can't be put on the remaining legal target.
