Answer:
A) three continents
Step-by-step explanation:
The Phoenician trade route included three continents: Europe, Africa, and Asia.
And more specifically: Mediterranean Europe, Northern Africa, and the Middle East, although some routes reached places even farer out.
These routes were a force of development during Antiquity, and led to market exchange among many different cultures, like the Gauls, the Italic peoples, the Iberians, the Bedouins, the Greeks, the Romans, the Egyptians, etc.
