Explanation:

King's allusion to Hitler's Germany and Hungarian freedom fighters is very effective. By contrasting legal (but immoral) actions under Hitler with illegal (but moral) actions of Hungarian fighters and his own hypothetical moral choice, he powerfully illustrates the distinction between legal and moral right, making his argument for civil disobedience in the face of unjust laws compelling. This allusion connects to widely recognized historical moral struggles, evoking strong emotional and ethical responses to emphasize his point about just and unjust laws.
