Lead can't be transmuted into gold - nor anything else, for that matter. But each of these processes involves three transmutations.
This hint could be transmuted into a hunt... or a host, or even a print. You should write down whatever's happening in the middle there.
Transmute selenium to potassium, then oxygen to carbon, then holmium to lithium to turn CHOOSE into CLICK.
Then try mapping out each middle transmutation on a familiar table, which you'll use again in the last step.
