Quizplus · Accepted Answer

The Greco-Persian conflict began in 499 BCE with the Ionian Revolt, in which the Greek city-states in Asia Minor rebelled against Persian rule. The conflict continued with the Persian invasions of Greece in 490 BCE and 480 BCE. Choice B) 480 BCE is also a correct answer, but A) is a more comprehensive answer, as it includes the precursor events to the full-scale invasions. Choice C) 429 BCE is incorrect, as by this time the major battles of the conflict had already taken place.
