Option 1) already satisfies. Taking option 1) brings the expected utility up above the threshold, so the satisficer is done.
If you add the extra requirement that the AI must never let the expected utility fall below the threshold in future, then the AI will simply blind itself or turn itself off, once the satisficing level is reached; then its expected utility will never fall, as no extra information ever arrives.

Sorry—a failure to reread the question on my part :-(
