You determine which creature to put counters on as the spell or ability that instructs you to bolster resolves.
Bolster itself doesn't target any creature, though some spells and abilities that bolster may have other effects that target creatures. For example, you could put counters on a creature with protection from white with Abzan Skycaptain's bolster ability.
