The correct answer is D, as the title that would best suit the period of Iraqi history from 1980 through 1990 is "The era of Iraqi agression".
This time could be called like that because during those 10 years Iraq invaded both Iran in 1980 (which led to a war that lasted until 1988), and Kuwait in 1990 (which led to the Gulf War, in which a coalition led by the United States defeated the Iraqi forces and restored the Kuwaiti territory).
