Answer:
Option D: The Minoans.
Step-by-step explanation:
After a decay in the Minoan civilization, Mycenaean managed to come to power in mainland and Crete. One of the main reasons was the eruption of the Thera volcano, which disaster had paramount consequences and ruined the Minoan civilization that at the time leaded the Greek peninsula, debilitating their sea power, commerce, economy, infrastructure, as well as a sudden decrease in population. The Mycenaeans were a military, well prepared civilization, and took advantage of this situation to invade the rest of the Minoans, conquering territorial plus naval power.
